Hi,
I build my MPCNC with above mentioned board and all works fine so far.
Except:
When I try to engrave pictures with my Laser the Laser does not turn on at all, it does turn on for Laser cutting.
I found the error in the gcode files:
They all start with
M3 S0
and then continues with using inline S commands, I can open the gcode and replace “M3 S0” with “M3 I” and then it engraves fine.
I could write “M3 I” in the start text in ESTLCAM, but LaserGBRL produces the exact same error, what configuration option am I missing here?
Regards
Martin
PS:
Oh and my Laser always turns on at max power with my MPCNC, thats anoying but the Lasers fault it goes to max power whenever there is no signal at all. Probably unfixabe, nut maybe someone has an idea. I put in a MOSFET for 3d printer beds to couple laser power to the laser ENA pin, but it does not switch, maybe not enough voltage on the pin? (upper left wifi pin, _29)
