how to adjust focus manually?
-
Hello. On my machine, the z-axis is adjusted manually and I would like to be able to programmatically turn on the laser with some minimum power for an indefinite time. The option using a virtual extruder did not work for me. In addition, this still implies switching on for a short time.

@Denis this is already on the work list for RRF 3.5. See also https://forum.duet3d.com/topic/22195/m3-control-for-laser-focus.

@dc42 Is there already a solution to the problem?

@FHesse I think the simplest solution for now is to set up a macro that does this:
- use M451 to switch out of laser mode to free up the laser control pin
- use M950 to configure the laser pin as GpOut pin
- use M42 to set the desired PWM on that pin
- use M291 to prompt the user to press OK when focusing is complete
- use M42 to turn off the laser
- use M950 to deconfigure the GpOut port
- use M452 to reselect laser mode.
