Optimizing Temperature Compensation Parameters Tutorial
This tutorial aims to optimize temperature compensation parameters to reduce temperature drift. The optimization process is time-consuming (over 1 hour). If your printer's temperature compensation meets your requirements, this operation may not be necessary.
Step 1: Paste the following macro into your configuration file:
[gcode_macro DATA_SAMPLE]
gcode:
M106 S255
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MAXIMUM=40
M106 S0
G28
G0 Z1
M104 S250
M140 S95
G4 P1000
IDM_STREAM FILENAME=data1
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MINIMUM=70
IDM_STREAM FILENAME=data1
M104 S0
M140 S0
M106 S255
G0 Z80
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MAXIMUM=40
M106 S0
G28 Z0
G0 Z2
M104 S250
M140 S95
G4 P1000
IDM_STREAM FILENAME=data2
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MINIMUM=70
IDM_STREAM FILENAME=data2
M104 S0
M140 S0
M106 S255
G0 Z80
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MAXIMUM=40
M106 S0
G28 Z0
G0 Z3
M104 S250
M140 S95
G4 P1000
IDM_STREAM FILENAME=data3
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MINIMUM=70
IDM_STREAM FILENAME=data3
M104 S0
M140 S0
M106 S255
G0 Z80
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MAXIMUM=40
M106 S0
G28 Z0
G0 Z5
M104 S250
M140 S95
G4 P1000
IDM_STREAM FILENAME=data4
TEMPERATURE_WAIT SENSOR='temperature_sensor IDM_coil' MINIMUM=70
IDM_STREAM FILENAME=data4
M104 S0
M140 S0
Step 2: Execute the macro. This will generate four files (data1, data2, data3, data4) in the klipper folder. This process takes a long time.
Step 3: Move the four generated files to the IDM folder in your user directory.
Step 4: Execute the following commands:
cd ~/IDM
~/klippy-env/bin/python arg_fit.py
(Ensure that you are using the latest script package before running. If not, git clone again.)
This will generate three parameters and an image named fit_result.png in the IDM folder. Note that this process requires significant computational power and time.
Step 5: Check the fit_result.png image for the fitting result. The first row shows the original data, and the second row shows the data after temperature compensation. Ensure that the fit is effective, and the offsets are controlled within a reasonable range.
Step 6: Copy the generated parameters to the [IDM] block in your configuration file. See the example below:
