Board: Cohesion3D mini
Firmware: Smoothie / Cluster_
Problem/ Question: I recently acquired a Mini board to replace the M2 Nano in my K40. Installed Lighburn trial on a Mac. First I had problems with the X and Y wiring and settings, but after some reading and trying, it was all fine, apart from a tiny little problem. With the default config.txt, when I start engraving or cutting, the head moves properly all the way, but it won’t fire the laser. Checking the config file, I found a line:
laser_module_enable, which was “false” by default. I changed it to “true”, now the laser fires, but the engraved image is just a black rectangle instead of the photo I tried. The edges are even darker, I tried to enable “overscan” in llightburn but that just made the rectangle bigger, with the same burnt edges. Now I can’t figure out what else can be wrong, can you please advise?
