I see what you say about the M106 command. In the window for the Laser tool I have set M106 S0 to turn laser off, m106 S255 to turn it on, and then in the laser power 120. I'm not sure why it puts the S0 on the line twice, but when I edit the gcode file to remove the duplicates, it still doesn't turn the laser on. Gcode is not controlling the laser.by Xonk61 - Laser Cutter Working Group
The plugin I use is JTech Photonics, a 100 mm square, exported to gcode yields the following: M106 S0 S0 G90 G21 G1 F400 G1 X12.3929 Y31.9528 G4 P0 M106 S255 S120 G4 P0 G1 F400.000000 G1 X40.2671 Y31.9528 G1 X40.2671 Y4.0785 G1 X12.3929 Y4.0785 G1 X12.3929 Y31.9528 G4 P0 M106 S0 S0 G1 F400 G1 X0 Y0 M18by Xonk61 - Laser Cutter Working Group
I have been piecing together a machine that I hope will one day become a 3D printer, but for now am just wanting to get the X Y axes to enable a laser engraver/cutter to function. All the framework, steppers, and assorted electrical bits have come from repurposed parts, old scanners, photocopiers, printers, etc. I did buy the Arduino Mega2650 with RAMPS board and LCD, as well as a laser moduleby Xonk61 - Laser Cutter Working Group
Mine was doing similarly, it wasn't until I looked at the solder connections on the card slot with a magnifier, that I noticed a non-contacting solder joint. A touch with a soldering iron, and all's well again.by Xonk61 - Firmware - Marlin
