@krohm-koala this could be linked to this bug.
Maybe try the version dc42 has linked to?

@jay_s_uk we will try, i'll keep you in touch

@jay_s_uk So, now we have a message that said "M3 commande not supported in machine mode laser"
maybe it's not supported anymore but it was really usefull for focus adjustement..

dc42

M3 commands with S parameter to set the laser power should still work in Laser mode.

@dc42 it's what it does before, we don't know why it doesn't work anymore, i only work on the machine in remote, the most of the time my friend do everything and tells me the result ^^ since we are on the last version, it doesn't work anymore, with the message ^^

@krohm-koala I can confirm I am also experiencing a problem with this - I've enabled laser mode with:

M452 C"duex.fan7" R255 F5000 S0		; Laser Mode

which I've connected to the input of a spare relay module and I am unable to switch the pin using M3 S255. If I enable laser mode with the pin inverted "!duex.fan7" I can hear the relay switching at the start of Laser mode but I still can't control it.

@educatingsavvas Have you tried to do a G1 Xxxx Sxxx to try if it turn on with a mouvement? it work for us, i assume it'll work for you. Even if it doesn't stay On, you can engrave

@krohm-koala Hiya - I swapped over to a spare heater terminal and generated a test code with the Opt Lasers g-code generator and I can see the red LED flickering on and off - for an image raster. Preventing the M3 command to turn on the laser is a safety feature so that makes sense now.

@educatingsavvas it make sense but, when you want to adjust your focus, it's a bit difficult during a mouvement ^^

@krohm-koala said in [3.3.0-rc2] M3-M5 gcode action:

hen you want to adjust your focus, it's a bit difficult duri

Does your laser have a Z-axis to adjust height? I'm planning for mine too - so eventually I'll do a test g-code that fine adjusts the laser height over multiple passes, and to than workout the offset from the top of the material being engraved/cut.
