Board: C3D Laserboard
Problem/ Question: I can engrave and cut vector images all day long, but when I try to engrave a picture in Lightburn the job stops about 30% in and gives me an Alarm 3. My laser is nowhere near the endstops, I have the laserboard mounted to the K40 with nylon screws, nylon spacers and nylon washers. There is absolutely no way it is grounding to the chassis of the K40.
I literally engraved and cut 12 projects in a row yesterday with absolutely no issue whatsoever. I then tried to engrave a photo. The first one came out just fine but I had cut against the grain by mistake and decided to flip the material over and engrave with the grain. about 30% in the job stopped.
I shut everything down for about 20 minutes and then tried it again. Same issue. No settings were changed. The only thing I did was flip the coaster over.
I posted this in the Lightburn forum and they said it was a problem with the board and not the software. Any help would be greatly appreciated.
