      @bearer said in Laser Works (but not from lightburn):

      my bad, marlin compat is a RRF thing https://duet3d.dozuki.com/Wiki/Gcode#Section_M555_Set_compatibility

      Oh, okay, I'll try that.
      Through the Lightburn forums I was also told that the next lightburn release will havean "inline" option in the Marlin profile that does exactly what we want:

      1b02cdad-9c75-4623-89b4-87d62b17dcb3-image.png

      So that's great too!

      and you're using https://duet3d.dozuki.com/Wiki/Gcode#Section_M452_Select_Laser_Printer_Mode ?

      Hmm, I see where you are going with this... I omitted the S1 parameter in the M452.
      That should do the trick... Thanks for this direction. There are so many thing to account for! 😉

      If you think trial and error is dangerous, try routine. That's even more so!

        Tested the S1 parameter in M452 and that works. Thanks @bearer for showing me.

        Extra questions for the experts:

        What is a nice clean method for having a nice clean low-power dot for focussing purposes? Anyone have a ready to use macro for that?

        And the second one is about the F parameter in M452. The specs of my lasermodule show a max PWM frequency of 20000Hz. Should I use that or is that some nonsense value? I see many people using different values here, but what values actualy make sense?

        If you think trial and error is dangerous, try routine. That's even more so!

          @DeltaCon Hey Guys, I'm trying to get this working with my laser as well and Lightburn is creating a G9 code in the Marlin version which is making it not work. Any ideas what I can do here? Running RRF 3+ on Duet 2 wifi - Thanks!

            @Jonty-0 where are you seeing that?
            I can generate gcode which works fine (apart from M7 and M8 not being implemented in RRF but they just get ignored)

              @jay_s_uk Hi Jay, so I tried to run the gcode file and it throws an error straight away. When I look in console it says Warning: M9: Command is not supported
              Cancelled printing file: etc/.. xxx/.xx
              Error: G0/G1: Target Position outside machine limits.

              Not sure why it's out of machine limits either but I was going to get to that next!

              Thanks.

                @Jonty-0 can you post an example file?
                check the gcode tab of device settings as well

                I usually manually home my laser and then use the workplace offsets to set the material position

                  @jay_s_uk Thanks mate. I think it's to do with the positioning somehow - I agree with you that - I think it's ignoring the M9 command but failing on machine limits.

                  I've homed my workbee, then moved it away from the corner a bit and set my work co-ordinates.

                  I think I'm setting lightburn wrong somehow. I'll have a play and come back to you! Thanks.

                    @Jonty-0 - OK I got it moving by playing with the positioning settings - so it's going round and round but laser not coming on. Here's an exampe of the gcode generated. Any ideas?

                          @Jonty-0 set your laser as sticky in M452 , i.e. add S1

                            @jay_s_uk Thanks jay - I think I'm there....it's coming on and off anyway as planned - I noticed that the frequency F1000 line in the gcode seems to be controlled by the mm/sec speed setting in Lightburn - when I changed it to 500mm, it changed the gcode to G1 x160.587 F500 and the laser didn't work.

                            Changed that to 1000 mm/s and it worked. Also added S1 too and works fine.

                            Thanks for your help mate, I really appreciate it. I can actually use the thing finally! Awesome. Owe you one. Thanks so much.
