How can I turn off laser while moving to another object?
Make sure you selected the appropriate machine profile in the settings base on the board. That’s will fill the gcode section with the apeopiate commands so that does not happen
Hi, so is in some cases m2 on m3 off or g01 on g00 off
Add M4 S0 in start gcode setting. Do Not use M3.
I had the same question. ( grbl 1.1) M4 S0 is already in the start gcode with the correct machine profile selected.
The answer was enabling laser mode in GRBL. Under gcode start add $32=1 under gcode end $32=0 I did this becasue in my case its a CNC machine and I want laser mode turned off otherwise. I do however have a problem where the laser takes 1/10 of a second to start cutting the material and thus leaves 1mm uncut at the start, advice on how to remedy that.
Try setting the minimum laser power to 1%, this way the laser control circuitry does not turn completely off when the laser is off
Thanks I’ll try that now. I have to say the $32 code is a very nice feature the cut on the right you can see how the paper was burnt but horizontal one is with laser mode enabled. It’s clean apart from the incomplete cuts https://plus.google.com/photos/105701171799483912820/albums/6492628885434347617/6492628891380350754
Oh nice there’s a pwm min in the latest version.
