Is enabled by setting pressure_advance: in the [extruder] section of the config.cfg to more than 0.
For a E3D titan i found values around 0.04 – 0.05 giving great results.
Toolpath prediction / Lookahead:
Can be dialed in by setting junction_deviation: in the [printer] section of the config.cfg
Basically lower values slow down cornering, higher values speed it up, i found 0.01 to be a good compromise.
M303 is supported in Klipper, after finishing an auto PID tune cycle like M303 E0 S215 C8 Klipper will report the correct PID values to Octopies GCode console and you can update your printer.cfg accordingly.
Additional hotend temperature controlled Fans:
Add any number of aditional fans for cooling stepsticks or the coldend by adding
Sections to your config.cfg
Theyll switch on once your hotend is set to 50c and switch of once its cooled below 50c.
Additional static PWM Pins:
Add any number of static pwm pins for controlling case lights f.e. by adding
where value sets the PWm cycle from 0 – 1 / 0 – 100%
Run-time configurable digital output pins ( “M42”)
Set pin in printer.cfg:
The pin to configure as a digital output. This parameter must be
The value to initially set the pin to during MCU configuration
(either 0 or 1). The default is 0 (for low voltage).
The value to set the pin to on an MCU shutdown event. The default
is 0 (for low voltage).
Afterwards you can control the pin via octoprints terminal like this:
SET_PIN PIN=my_pin VALUE=0
