Copy .py files to klipper/klippy/extras

Add to beginning of printer.cfg

[heaters_extra]
[pid_calibrate_extra]

Use [fan_extra] instead of [fan]

Add to beginning of printer.cfg

[rotation_distance]

Restart klipper service, RESTART command won't activate modules!

Use [heater_fan_extra extruder] instead of [heater_fan extruder]

gcode commands:

SET_HEATER_FAN_SPEED FAN=extruder SPEED=[0 - 1.0]

heater option:

control: pid_v

Activates Velocity PID

gcode commands:

SET_HEATER_PARAMS HEATER= KP= KI= KD=

for pid controlled heater

SET_HEATER_PARAMS HEATER= MAX_DELTA=

for bang-bang heater

GET_HEATER_PARAMS HEATER=

Prints current heater params

gcode command

PID_CALIBRATE_EXTRA

same options as default PID_CALIBRATE

Scaling fan value between off_below and max_power. For example with followong config:

[fan_extra]
off_below: 0.2
max_power: 0.8
...

Calling M106 S1 will set output to 0.2, M106 S255 will set output to 0.8, and all values between would be linear scaled accordingly.

Calculate and apply new rotation distance based on extrude calibration

ROTATION_DISTANCE_CALC EXTRUDER=extruder EXTRUDED=101 REQUESTED=100

Save new rotation_distance value to config file

ROTATION_DISTANCE_SAVE EXTRUDER=extruder
