Klipper Pressure Advance calibration object

thingiverse

Use this object and the TUNING_TOWER command to determine an optimal ADVANCE value for Klipper's Pressure Advance feature. Add these three statements to your start gcode and print the object in vase mode (no bottom layers to be fast) @ 100 mm/s (you may want to add a brim for bed adhesion). >SET_VELOCITY_LIMIT SQUARE_CORNER_VELOCITY=1 ACCEL=500 >SET_PRESSURE_ADVANCE ADVANCE_LOOKAHEAD_TIME=0 ADVANCE=0.0 >TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=0.05 The object is 25mm high, so the ADVANCE value will change gradually from 0 at the bottom to 1.25 at the top. Measure the height (in mm) where corners look best and multiply by 0.05. That will give you your ADVANCE value. Note that TUNING_TOWER feature is a relatively recent addition to Klipper, so you may have to bring your installation up-to-date. Also, check for the most recent syntax of used commands.
