-###### STANDARD INPUT_SHAPER CALIBRATIONS ######
-################################################
-# Written by Frix_x#0161 #
-# @version: 1.4
-
-# CHANGELOG:
-#   v1.4: added possibility to only run one axis at a time for the axes shaper calibration
-#   v1.3: added possibility to override the default parameters
-#   v1.2: added EXCITATE_AXIS_AT_FREQ to hold a specific excitating frequency on an axis and diagnose mechanical problems
-#   v1.1: added M400 to validate that the files are correctly saved to disk
-#   v1.0: first version of the automatic input shaper workflow
-
-
-### What is it ? ###
-# This macro helps you to configure the input shaper algorithm of Klipper by running the tests sequencially and calling an automatic script
-# that generate the graphs, manage the files and so on. It's basically a fully automatic input shaper calibration workflow.
-# Results can be found in your config folder using FLuidd/Maisail file manager.
-
-# The goal is to make it easy to set, share and use it.
-
-# Usage:
-#   1. Call the AXES_SHAPER_CALIBRATION macro, wait for it to end and compute the graphs. Then look for the results in the results folder.
-#   2. Call the BELTS_SHAPER_CALIBRATION macro, wait for it to end and compute the graphs. Then look for the results in the results folder.
-#   3. If you find out some strange noise, you can use the EXCITATE_AXIS_AT_FREQ macro to diagnose the origin

-###### VIBRATIONS AND SPEED OPTIMIZATIONS ######
-################################################
-# Written by Frix_x#0161 #
-# @version: 2.1
-
-# CHANGELOG:
-#   v2.1: allow decimal entries for speed and increment and added the E axis as an option to be neasured
-#   v2.0: added the possibility to measure mutliple axis
-#   v1.0: first speed and vibrations optimization macro
-
-
-### What is it ? ###
-# This macro helps you to identify the speed settings that exacerbate the vibrations of the machine (ie. where the frame resonate badly).
-# It also helps to find the clean speed ranges where the machine is silent.
-# I had some strong vibrations at very specific speeds on my machine (52mm/s for example) and I wanted to find all these problematic speeds
-# to avoid them in my slicer profile and finally get the silent machine I was dreaming!
-
-# It works by moving the toolhead at different speed settings while recording the vibrations using the ADXL chip. Then the macro call a custom script
-# to compute and find the best speed settings. The results can be found in your config folder using Fluidd/Mainsail file manager.
-
-# The goal is to make it easy to set, share and use it.
-
-# This macro is parametric and most of the values can be adjusted with their respective input parameters.
-# It can be called without any parameters - in which case the default values would be used - or with any combination of parameters as desired.
-
-# Usage:
-#   1. DO YOUR INPUT SHAPER CALIBRATION FIRST !!! This macro should not be used before as it would be useless and the results invalid.
-#   2. Call the VIBRATIONS_CALIBRATION macro with the speed range you want to measure (default 20 to 200mm/s with 2mm/s increment).
-#      Be carefull about the Z_HEIGHT variable that default to 20mm -> if your ADXL is under the nozzle, increase it to avoid a crash of the ADXL on the bed of the machine.
-#   3. Wait for it to finish all the measurement and compute the graph. Then look at it in the results folder.

-#           automated peak detection, etc...
-#         - added a full spectrogram of the signal on the bottom to allow deeper analysis
-#   v1.0: first version of this script inspired from the official Klipper

-###### INPUT SHAPER KLIPPAIN WORKFLOW ######
-############################################
-# Written by Frix_x#0161 #
-# @version: 2.0
-
-# CHANGELOG:
-#   v2.0: new version of this as a Python script (to replace the old bash script) and implement the newer and improved shaper plotting scripts
-#   v1.7: updated the handling of shaper files to account for the new analysis scripts as we are now using raw data directly
-#   v1.6: - updated the handling of shaper graph files to be able to optionnaly account for added positions in the filenames and remove them
-#         - fixed a bug in the belt graph on slow SD card or Pi clones (Klipper was still writing in the file while we were already reading it)
-#   v1.5: fixed klipper unnexpected fail at the end of the execution, even if graphs were correctly generated (unicode decode error fixed)
-#   v1.4: added the ~/klipper dir parameter to the call of graph_vibrations.py for a better user handling (in case user is not "pi")
-#   v1.3: some documentation improvement regarding the line endings that needs to be LF for this file
-#   v1.2: added the movement name to be transfered to the Python script in vibration calibration (to print it on the result graphs)
-#   v1.1: multiple fixes and tweaks (mainly to avoid having empty files read by the python scripts after the mv command)
-#   v1.0: first version of the script based on a Zellneralex script
-
-# Usage:
-#   This script was designed to be used with gcode_shell_commands directly from Klipper
-#   Parameters availables:
-#      BELTS       - To generate belts diagrams after calling the Klipper TEST_RESONANCES AXIS=1,(-)1 OUTPUT=raw_data
-#      SHAPER      - To generate input shaper diagrams after calling the Klipper TEST_RESONANCES AXIS=X/Y OUTPUT=raw_data
-#      VIBRATIONS  - To generate vibration diagram after calling the custom (Frix_x#0161) VIBRATIONS_CALIBRATION macro

-## Installation
-
-For those not using the full [Klippain](https://github.com/Frix-x/klippain), follow these steps to integrate this Shake&Tune module in your setup:
-  1. Run the install script over SSH on your printer:
-     ```bash
-     wget -O - https://raw.githubusercontent.com/Frix-x/klippain-shaketune/main/install.sh | bash
-     ```
-  2. Append the following to your `printer.cfg` file:
-     ```
-     [include K-ShakeTune/*.cfg]
-     ```
-  3. Optionally, if you want to get automatic updates, add the following to your `moonraker.cfg` file:
-     ```
-     [update_manager Klippain-ShakeTune]
-     type: git_repo
-     path: ~/klippain_shaketune
-     channel: beta
-     origin: https://github.com/Frix-x/klippain-shaketune.git
-     primary_branch: main
-     managed_services: klipper
-     install_script: install.sh
-     ```
 
   > **Note**:
   >
-   > If already using my old IS workflow scripts, please remove everything before installing this new module. This include the macros, the Python scripts, the `plot_graph.sh` and the `[gcode_shell_command plot_graph]` section.
+  > Be aware that Shake&Tune uses the [Gcode shell command plugin](https://github.com/dw-0/kiauh/blob/master/docs/gcode_shell_command.md) under the hood to call the Python scripts that generate the graphs. While my scripts should be safe, the Gcode shell command plugin also has great potential for abuse if not used carefully for other purposes, since it opens shell access from Klipper.
+
+## Installation
+
+Follow these steps to install the Shake&Tune module in your printer:
+  1. Be sure to have a working accelerometer on your machine and a `[resonance_tester]` section defined. You can follow the official [Measuring Resonances Klipper documentation](https://www.klipper3d.org/Measuring_Resonances.html) to configure it.
+  1. Install the Shake&Tune package by running over SSH on your printer:
+     ```bash

 ## Usage
 
 Ensure your machine is homed, then invoke one of the following macros as needed:
-  - `BELTS_SHAPER_CALIBRATION` for belt resonance graphs, useful for verifying belt tension and differential belt paths behavior.
+  - `AXES_MAP_CALIBRATION` to automatically find Klipper's `axes_map` parameter for your accelerometer orientation (be careful, this is experimental for now and known to give bad results).
-  - `AXES_SHAPER_CALIBRATION` for input shaper graphs to mitigate ringing/ghosting by tuning Klipper's input shaper system.
+  - `COMPARE_BELTS_RESPONSES` for a differential belt resonance graph, useful for checking relative belt tensions and belt path behaviors on a CoreXY printer.
-  - `VIBRATIONS_CALIBRATION` for machine vibration graphs to optimize your slicer speed profiles.
+  - `AXES_SHAPER_CALIBRATION` for standard input shaper graphs, used to mitigate ringing/ghosting by tuning Klipper's input shaper filters.
-  - `EXCITATE_AXIS_AT_FREQ` to sustain a specific excitation frequency, useful to let you inspect and find out what is resonating.
+  - `CREATE_VIBRATIONS_PROFILE` for vibrations graphs as a function of toolhead direction and speed, used to find problematic ranges where the printer could be exposed to more VFAs and optimize your slicer speed profiles and TMC driver parameters.
+  - `EXCITATE_AXIS_AT_FREQ` to maintain a specific excitation frequency, useful to inspect and find out what is resonating.

+## Additional macros
+
+### AXES_MAP_CALIBRATION (experimental)
+
+All graphs generated by this package show plots based on accelerometer measurements, typically labeled with the X, Y, and Z axes. It's important to note that if the accelerometer is rotated, its axes may not align correctly with the machine axes, making the plots more difficult to interpret, analyze, and understand. The `AXES_MAP_CALIBRATION` is designed to automatically measure the alignement of the accelerometer in order to set it correctly.
+
+  > **Note**:
+  >
+  > This misalignment doesn't affect the measurements because the total sum across all axes is used to set the input shaper filters. It's just an optional but convenient way to configure Klipper's `[adxl345]` (or whichever accelerometer you have) "axes_map" parameter.
+
+Here are the parameters available when calling this macro:
+
+| parameters | default value | description |
+|-----------:|---------------|-------------|
+|Z_HEIGHT|20|z height to put the toolhead before starting the movements. Be careful, if your accelerometer is mounted under the nozzle, increase it to avoid crashing it on the bed of the machine|
+|SPEED|80|speed of the toolhead in mm/s for the movements|
+|ACCEL|1500 (or max printer accel)|accel in mm/s^2 used for all the moves|
+|TRAVEL_SPEED|120|speed in mm/s used for all the travels moves|
+|ACCEL_CHIP|"adxl345"|accelerometer chip name in the config|
+
+The machine will move slightly in +X, +Y, and +Z, and output in the console: `Detected axes_map: -z,y,x`.
+
+Use this value in your `printer.cfg` config file:
+```
+[adxl345] # replace "adxl345" by your correct accelerometer name
+axes_map: -z,y,x
+```
+
+### EXCITATE_AXIS_AT_FREQ
+
+The `EXCITATE_AXIS_AT_FREQ` macro is particularly useful for troubleshooting mechanical vibrations or resonance issues. This macro allows you to maintain a specific excitation frequency for a set duration, enabling hands-on diagnostics. By touching different components during the excitation, you can identify the source of the vibration, as contact usually stops it.
+
+Here are the parameters available when calling this macro:
+
+| parameters | default value | description |
+|-----------:|---------------|-------------|
+|FREQUENCY|25|excitation frequency (in Hz) that you want to maintain. Usually, it's the frequency of a peak on one of the graphs|

 ## Generalities on the graphs
 
 When tuning Input Shaper, keep the following in mind:
-  1. **Focus on the shape of the graphs, not the exact numbers**. There could be differences between ADXL boards or even printers, so there is no specific "target" value. This means that you shouldn't expect to get the same graphs between different printers, even if they are similar in term of brand, parts, size and assembly.

+  1. Small differences between consecutive test runs are normal, as accelerometer quality and sensitivity is quite variable between boards.
   1. Perform the tests when the machine is heat-soaked and close to printing conditions, as the temperature will impact the machine components such as belt tension or even the frame that is known to expand a little bit.
   1. Avoid running the toolhead fans during the tests, as they introduce unnecessary noise to the graphs, making them harder to interpret. This means that even if you should heatsoak the printer, you should also refrain from activating the hotend heater during the test, as it will also trigger the hotend fan. However, as a bad fan usually introduce some vibrations, you can use the test to diagnose an unbalanced fan as seen in the [Examples of Input Shaper graphs](./macros/axis_tuning.md) section.
-  1. Ensure the accuracy of your ADXL measurements by running a `MEASURE_AXES_NOISE` test and checking that the result is below 100 for all axes. If it's not, check your ADXL board and wiring before continuing.
+  1. Ensure the accuracy of your accelerometer measurements by running a `MEASURE_AXES_NOISE` test and checking that the result is below 100 for all axes. If it's not, check your accelerometer board and wiring before continuing.
   1. The graphs can only show symptoms of possible problems and in different ways. Those symptoms can sometimes suggest causes, but they rarely pinpoint the exact issues. For example, while you may be able to diagnose that some screws are not tightened properly, you will unlikely find which exact screw is problematic using only these tests. You will most always need to tinker and experiment.
   1. Finally, remember why you're running these tests: to get clean prints. Don't become too obsessive over perfect graphs, as the last bits of optimization will probably have the least impact on the printed parts in terms of ringing and ghosting.

-Input Shaping algorithms work by suppressing a single resonant frequency (or a range around a single resonant frequency). When setting the filter, **the primary goal is to target the resonant frequency of the toolhead and belts system** (see the [theory behind it](#theory-behind-it)), as this has the most significant impact on print quality and is the root cause of ringing.

-When setting up Input Shaper, it is important to consider the accelerometer mounting point. There are mainly two possibilities, each with its pros and cons:
+Choosing the accelerometer's mounting point is important. There are currently three mounting strategies, each offering distinct advantages:
 
-| Directly at the nozzle tip | Near the toolhead's center of gravity |
+| Mounting Point | Advantages | Considerations |
-| --- | --- |
+| --- | --- | --- |
-| This method provides a more accurate and comprehensive measurement of everything in your machine. It captures the main resonant frequency along with other vibrations and movements, such as toolhead wobbling and printer frame movements. This approach is excellent for diagnosing your machine's kinematics and troubleshooting problems. However, it also leads to noisier graphs, making it harder for the algorithm to select the correct filter for input shaping. Graphs may appear worse, but this is due to the different "point of view" of the printer's behavior. | I personally recommend mounting the accelerometer in this way, as it provides a clear view of the main resonant frequency you want to target, allowing for accurate input shaper filter settings. This approach results in cleaner graphs with less visible noise from other subsystem vibrations, making interpretation easier for both automatic algorithms and users. However, this method provides less detail in the graphs and may be slightly less effective for troubleshooting printer problems. |
+| **Directly at the nozzle tip** | Provides a comprehensive view of all machine vibrations, including the main resonance, but also toolhead wobbling and global frame movements. Ideal for diagnosing kinematic issues and troubleshooting. | Results in noisier data, which may complicate the final Input Shaping filter selection on machines that are not perfect and/or not fully rigid. |
+| **Near the toolhead's center of gravity** | Provides a view of mostly only the primary resonant frequencies of the toolhead and belts, allowing precise filter selection for Input Shaping. The data is often cleaner, with only severe mechanical issues or very problematic toolhead wobble visible on the graphs. | May provide less detail on secondary vibrations (which have a fairly minor effect on ringing) and may be less effective in diagnosing unrelated mechanical problems. |
+| **Integrated accelerometer on a CANBus Board** | Simple and effective, requires no additional installation and always available. Can help for diagnosing issues like those caused by bowden tubes, umbillical coords and cable chains. If toolhead is very rigid, measurements are close enough to those of the center of gravity. | Not accurate for a detailed analysis or diagnosing mechanical issues due to distance from the nozzle tip and potential noise from attached components. |
 
-A suggested workflow is to first use the nozzle mount to diagnose mechanical issues, such as loose screws or a bad X carriage. Once the mechanics are in good condition, switch to a mounting point closer to the toolhead's center of gravity for setting the input shaper filter settings by using cleaner graphs that highlights the most impactful frequency.
+While you should usually try to focus on the toolhead/belts mechanical subsystem for resonance mitigation (since it has the most impact on ringing and print quality), you don't want to overlook the importance of nozzle tip measurements for other sources of vibration. Indeed, if resonance analysis results vary a lot between mounting points, reinforcing the toolhead's rigidity to minimize wobbling and vibrations is recommended. Here is a strategy that attempts to methodically address mechanical issues and then allow for the day-to-day selection of input shaping filters as needed: 
+  1. **Diagnosis phase**: Begin with the nozzle tip mount to identify and troubleshoot mechanical issues to ensure the printer components are healthy and the assembly is well done and optimized.
+  1. **Filter selection phase**: If the graphs are mostly clean, you can transition to a mounting point near the toolhead's center of gravity for cleaner data on the main resonance, facilitating accurate Input Shaping filter settings. You can also consider the CANBus integrated accelerometer for its simplicity, especially if the toolhead is particularly rigid and minimally affected by wobble.

 ### Toolhead or TAP wobble
 
-The [Voron TAP](https://github.com/VoronDesign/Voron-Tap) can introduce anomalies to input shaper graphs, notably on the X graph. Its design with an internal MGN rail introduces a separate and decoupled mass, leading to its own resonance, typically around 125Hz. Combatting this can be pretty challenging, but using premium components and a careful assembly can help mitigate the issue. Ensure you employ a good quality and well-preloaded TAP MGN rail for optimal assembly stiffness, coupled with genuine and strong N52 magnets (avoid lower-quality N35 or N45 substitutes often found on chinese marketplaces). Prioritize careful assembly and consider using the TAP Rev8 version or above.

-Additionally, without a Voron TAP, small 125hz peaks can sometimes tie back to the toolhead itself. Common culprits include loosely fitted screws or a bad quality X linear MGN axis that can have some play in the carriage, leading to slight toolhead wobbling. This is often represented as a Z component in the graphs.
+Small 125Hz peaks are also most often due to the toolhead itself, since most toolheads are about the same mass. Common culprits include loose screws or a bad quality X linear MGN axis that can have some play in the carriage, causing the toolhead to wobble slightly. This is often shown as a Z component in the graphs and can be amplified by the bowden tube or an umbilical that applies some forces on top of the toolhead.
 
-If your graph shows this kind of anomalies, begin by disassembling the toolhead up to the X carriage. Check for any looseness, then reassemble, ensuring everything is tightened properly for a rigid assembly. Also, don't forget to check your extruder and validate its assembly as well. Finally, ensure you have some filament loaded during measurements to prevent extruder gear vibrations.
+If your graph shows this kind of anomalies:
+  1. Start by looking at the bowden tube and umbilical to make sure they are not exerting excessive force on the toolhead. You want them to create no drag or as little drag as possible.
+  1. If that's not enough, continue disassembling the toolhead down to the X carriage. Check for any loose or cracked parts, then reassemble, making sure everything is tightened properly for a rigid assembly.
+  1. When using TAP, this can be quite a challenge to combat, but using quality components and careful assembly can help mitigate the problem. In particular, be sure to use a well-preloaded TAP MGN rail for maximum rigidity, coupled with genuine and strong N52 magnets that are properly seated and not loose.

+### Fan behavior
 
-The presence of an unbalanced or badly running fan can be directly observed in the graphs. While you should let the toolhead fans off during the final IS tuning, you can use this test to validate their correct behavior: an unbalanced fan usually add some very thin peak around 100-150Hz that disapear when the fan is off. Also please note that an unbalanced fan constant frequency is manifested as a vertical line on the bottom spectrogram.
+The presence of an unbalanced or poorly running fan can be directly observed in the spectrogram:
+  1. A properly running fan can be seen as a vertical purple line on the spectrogram that doesn't shine too much. This is perfectly normal because it's running at a constant speed (i.e. constant frequency) throughout the test. The purple color means that its vibration energy is quite low and should not cause any problems. There are no corresponding peaks on the top graph.
+  1. When the vertical line on the spectrogram starts to become yellowish, pay special attention to the top graph to see if there is a corresponding peak. In the example from the middle below, the fan is in the limit with a very small bump corresponding to it. So it may or may not cause trouble... Do some test prints and look for VFAs, if you find some you may want to replace the fan.
+  1. If the vertical line is bright orange/yellow, there will most likely be a corresponding thin but high peak on the top graph. This fan is out of balance, producing bad vibrations and needs to be replaced.

However, a detailed comparison of their datasheets and practical measurements paints a more complex picture: the LIS2DW boasts greater sensitivity, but it has a lower sampling rate and produce significant aliasing that results in a "lightshow" effect on the spectrogram, characterized by multiple spurious resonance lines parallel to the main resonance, accompanied by intersecting interference lines that distort the harmonic profile.
+
+While in most cases the overall shape of the upper resonance curve, including resonant frequency and damping ratio, should be close to reality with fairly similar input shaping filter recommendations, this aliasing makes it difficult to identify subtle details and complicates the diagnosis of mechanical problems. In particular, it introduces a potential misinterpretation of "[binding](#low-frequency-energy)" due to a global offset of the curve. In the worst cases (see the last example below), the aliasing is too severe and adds too much noise to the graph, making it unusable.

+  > It seems that some LIS2DW chips are better than others: in some cases aliasing is not a problem, but it can also be very problematic and lead to bad graphs, as seen in the "Extreme Aliasing" example below.

 ### Crazy graphs and miscs
 
 The depicted graphs are challenging to analyze due to the overwhelming noise across the spectrum. Such patterns are often associated with an improperly assembled and non-squared mechanical structure. To address this:
   1. Refer to the [Low frequency energy](#low-frequency-energy) section for troubleshooting steps.
-  2. If unresolved, consider disassembling the entire gantry, inspect the printed and mechanical components, and ensure meticulous reassembly. A thorough and careful assembly should help alleviate the issue. Measure again post-assembly for changes.

 Also please note that for this kind of graphs, as they are mainly consisting of noise, Klipper's algorithm recommendations must not be used and will not help with ringing. You will need to fix your mechanical issues instead!

+## Graphs description
+
+The `CREATE_VIBRATIONS_PROFILE` macro results are constituted of a set of 6 plots. At the top of the figure you can also see all the detected motor, current and TMC driver parameters. These notes are just for reference in case you want to tinker with them and don't forget what you changed between each run of the macro.
+
+![](../images/vibrations_example.png)
+
+### Global Speed Energy Profile
+
+| Example | description |
+|:-----|-------------|
+|![](../images/vibrations_graphs/global_speed_energy_profile.png)|This plot shows the relationship between toolhead speed (mm/s) and vibrational energy, providing a global view of how speed impacts vibration across all movements. By using speeds from the green zones, your printer will run more smoothly and you will minimize vibrations and related fine artifacts in prints|
+
+This graph is the most important one of this tool. You want to use it to adapt your slicer profile, especially by looking at the "vibration metric" curve, that will helps you find which speeds can be problematic for your printer. Here's the magic behind it, broken down into two key parts:
+  1. **Spectrum Variance**: This is like the mood ring of your printer, showing how the vibes (a.k.a vibrations) change when printing from different angles. If the "vibration metric" is low, it means your printer is keeping its cool, staying consistent no matter the angle. But if it spikes, it's a sign that some angles are making your printer jitter more than a caffeinated squirrel. *Imagine it like this: You're looking for a chill party vibe where the music's good at every angle, not one where you turn a corner and suddenly it's too loud or too soft.*
+  2. **Spectrum Max**: This one's about the max volume of the party, or how loud the strongest vibration is across all angles at any speed. We're aiming to avoid the speeds that crank up the volume too high, causing a resonance rave in the motors. *Think of it this way: You don't want the base so high that it feels like your heart's going to beat out of your chest. We're looking for a nice background level where everyone can chat and have a good time.*
+
+And why do we care so much about finding these speeds? Because during a print, the toolhead will move in all directions depending on the geometry, and we want a speed that's like a good friend, reliable no matter what the situation. Fortunately, since the motors in our printers share their vibes without non-linear mixing and just add up (think of it as each doing its own dance without bumping into each other), we can find those happy green zones on the graph: these are the speeds that keep the vibe cool and the energy just right, making them perfect for all your print jobs.
+
+### Polar Angle Energy Profile
+
+| Example | description |
+|:-----|-------------|
+|![](../images/vibrations_graphs/polar_angle_energy_profile.png)|Shows how vibrational energy varies with the direction where the toolhead is running. It helps in identifying angles that produce less vibration, and potentially detect assymetries in the belt paths for a CoreXY printer|
+
+This plot is like your go-to playlist for finding those angles where the vibe is just right. But here's the thing: when printing, your toolhead will groove in all directions and angles, depending on the geometry of your parts, so sticking to just one angle isn't possible. My tip to make the most of this chart for your prints: if you're working on something rectangular, try to align it so that most of the edges match the angles that's least likely to make your printer jitter. For those sleek CoreXY printers, aiming for 45/135 degrees is usually a hit, while the trusty Cartesian printers groove best at 0/90 degrees. And for everything else? Well, there's not much more to do here except rely on the [Global Speed Energy Profile chart](#global-speed-energy-profile) to tune your slicer profile speeds instead.
+
+Now, onto the symmetry indicator. Think of this tool as the dance coach for your printer, especially designed for those with a symmetrical setup like CoreXY models. It's all about using some pretty neat math (cross-correlation, to be exact) to check out the vibes from both sides of the dance floor. Picture it as a top-notch party dancer, scanning the room at every angle, judging each dancer, and only giving top marks when everyone is perfectly in sync. This tool is ace at catching any sneakiness in your motor control or belt path, highlighting any "butterfly" shapes or even the slightest variations in the motors' resonance patterns. It's like having a magnifying glass that points out exactly where the party fouls are, helping you to fix them and keep your prints rolling out smooth and stunning.
+
+### Angular Speed Energy Profiles
+
+| Example | description |
+|:-----|-------------|
+|![](../images/vibrations_graphs/angular_speed_energy_profile.png)|Provides a detailed view of how energy distribution changes with speed for specific angles. It's useful for fine-tuning speeds for different directions of motion, or for tracking and diagnosing your printer's behavior across the major axes|
+
+This chart is like a snapshot, capturing the vibe at certain angles of your printing party. But remember, it's just a glimpse into a few specific angles and doesn't fully reveal the whole dance floor where the toolhead moves in every direction, vibing with the unique geometry of your parts. So, think of it as a way to peek into how everyone's grooving in each corner of the party. It's great for a quick check-up to see how the vibe is holding up, but when it comes to setting the rhythm of your slicer speeds, you're going to want to use the [Global Speed Energy Profile chart](#global-speed-energy-profile) instead.
+
+### Vibrations Heatmaps
+
+| Example | description |
+|:-----|-------------|
+|![](../images/vibrations_graphs/vibrations_heatmaps.png)|Both plots provides a comprehensive overview of vibrational energy across speeds and angles. It visually identifies zones of high and low energy, aiding in the comprehensive understanding of the printer motors behavior. It's what is captured by the accelerometer and the base of all the other plots|
+
+Both heatmaps lay down the vibe of vibrational energy across all speeds and angles, painting a picture of how the beat spreads throughout your printer's dance floor. The polar heatmap gives you a 360-degree whirl of the action, while the regular one lays it out in a classic 2D groove, yet both are vibing to the same tune and showing you where the energy's hot and popping and where it's cool and mellow across your printer's operational range. Think of it as the unique fingerprint of your motor's behavior captured by the accelerometer, it's the raw rhythm of your printer in action.
+
+Because the scale is both normalized and logarithmic, you're looking for a heatmap (or spectrogram) that has a cool, consistent "orangish" vibe throughout, signaling not so much change over the spectrum with fairly low motor resonances. See areas in your heatmap that swing from deep purple/black to bright white/yellow? That's a sign that your printer motors are hitting high resonances at certain angles and speed combinations that are above the baseline vibrations outside of those areas. But remember, this is just the lay of the land, a snapshot of the scene: tweaking this vibe directly may not be easy, but you can still [play around with the TMC driver parameters](#improving-the-results) to adjust the beats and find a smoother rhythm.
+
+### Motor Frequency Profile
+
+| Example | description |
+|:-----|-------------|
+|![](../images/vibrations_graphs/motor_frequency_profile.png)|Identifies the resonant frequencies of the motors and their damping ratios. Informative for now, but will be used later|
+
+For now, this graph is purely informational and is a measurement of the motor's natural resonance profile. Think of this plot as a sneak peek at the inner workings of your printer's dance floor. It's not quite ready to hit the main stage for practical use, but just you wait... Keep an eye on this chart as it hints at future remixes where you'll get to play DJ and tweak and tune your printer's performance like never before.
+
+
+## Improving the results
+
+These graphs essentially depict the behavior of the motor control on your machine. While there isn't much room for easy adjustments to enhance them, most of you should only utilize them to configure your slicer profile to avoid problematic speeds.
+
+However, if you want to go the rabbit hole, as the data in these graphs largely hinges on the type of motors, their physical characteristic and the way they are controlled by the TMC drivers black magic, there are opportunities for optimization. Tweaking TMC parameters allow to adjust the peaks, enhance machine performance, or diminish overall machine noise. For this process, I recommend to directly use the [Klipper TMC Autotune](https://github.com/andrewmcgr/klipper_tmc_autotune) plugin, which should simplify everything considerably. But keep in mind that it's still an experimental plugin and it's not perfect.
+
+For individuals inclined to reach the bottom of the rabbit hole and that want to handle this manually, the use of an oscilloscope is mandatory. Majority of the necessary resources are available directly on the Trinamics TMC website:
+  1. You should first consult the datasheet specific to your TMC model for guidance on parameter names and their respective uses.
+  2. Then to tune the parameters, have a look at the application notes available on their platform, especially [AN001](https://www.trinamic.com/fileadmin/assets/Support/AppNotes/AN001-SpreadCycle.pdf), [AN002](https://www.trinamic.com/fileadmin/assets/Support/AppNotes/AN002-StallGuard2.pdf), [AN003](https://www.trinamic.com/fileadmin/assets/Support/AppNotes/AN003_-_DcStep_Basics_and_Wizard.pdf) and [AN009](https://www.trinamic.com/fileadmin/assets/Support/AppNotes/AN009_Tuning_coolStep.pdf).
+  3. For a more comprehensive understanding, you might also want to explore [AN015](https://www.trinamic.com/fileadmin/assets/Support/AppNotes/AN015-StealthChop_Performance.pdf) and [AN021](https://www.trinamic.com/fileadmin/assets/Support/AppNotes/AN021-StealthChop_Performance_comparison_V1.12.pdf ), although they are more geared towards enhancing comprehension than calibration, akin to the TMC datasheet.
