Klipper pressure advance tuning tower

Slicer settings:

Vase mode

1 botom layer or brim

0.2 layer height

max speed: 100mm/s

Prepare for the test by issuing the following G-Code command:

SET_VELOCITY_LIMIT SQUARE_CORNER_VELOCITY=1 ACCEL=500

This command makes the nozzle travel slower through corners to emphasize the effects of extruder pressure. Then for printers with a direct drive extruder run the command:

TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=.005

For long bowden extruders use:

TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=.020

The pressure_advance value can then be calculated as pressure_advance = <start> + <measured_height> * <factor>. (For example, 0 + 12.90 * .020 would be .258.)
