sheet cam and grbl

[hillbilly112]

I built a plasma cutter using an Arduino
using inkscape or laser burn to degisn, I then export as a dxf file I then open sheetcam and adjust parameters 2nd to last operations I pick GRBL for my post processior, run post save send to universal g code sender

I then hit run program,,,the machine will move to my 4 inner holes then proceed to go to the final path and stop but never a torch light ????

if I use lightburn I can cut out traces and names in stencil but nothing with a stop an go.
universal g code sender using a trace cut again works but no stop and goes

ive been at this point for 2 months and am very frustrated with so many post somebody should be able to help me

can you post your gcode?

sounds like your issue is M3 and M5 not being seen by GRBL (you may need to change the post processor so that it issues whatever GRBL needs to see to turn the torch on and off)
