@Royassas well spotted, and sorry for the wasted time! I’ve accepted your edits to the Gcode page.

It probably would have helped if sending M452 with no parameters reported the current settings, then you would have seen the frequency was not changing, but M451/452/453 were originally defined (not by us) to have no parameters. So they switch modes without any. M450 reports the mode (CNC/laser/3D printer) but not the parameters. I’ve asked @dc42 if he can add parameter reporting to M450.

Might this be because of the sticky S setting in laser mode definition?

Yes. If you set the sticky feature then the S parameter is remembered across G0 moves. This is IMO a dangerous thing to do, but unfortunately it's what the programs that generate GCodes for laser cutters and engravers expect. I'd much rather those programs generated the S parameter on every G1 move that needs the laser on, which would be the safe thing to do.

You can use command G1 S0 at the end of your GCode file (or in your stop.g file, if your program ends with a M0 command) to reset the laser power to zero.

It's occurred to me that the firmware could remember the laser power setting separately for each input channel, so I may implement this in a future firmware version. I'll also change it to reset the remembered laser power to zero automatically at the end of a job, if it doesn't already.

@Royassas said in Duet 3 Laser and PWM Frequency:

@bearer Couldn't find an acceptable machine profile yet. Engraving and cutting probably needs the speed-adjusted update thats scheduled to come soon to duet3 firmware as @dc42 mentioned in other posts.

It's been working in RRF3 for several months, not just on Duet 3 but on Duet WiFi/Ethernet too.

Not yet but I am planning to upgrade to a duet board shortly.
I expect there to be some sort of post processing required to get it fully compatible.

I think the profiles used with Smoothieboard and grbl may work as-is.
