Hi, I am using an Alfawise C10 and I just changed the motherboard which is running with GRBL 1.1f.
The laser power is stuck at 20% and doesn’t burn when I run a laser engraving. I tried all the troubleshooting stuff I found on the forum but so far I haven’t been able to solve this issue. It was working great before the upgrade. I also checked the config using the command line $$ and everything is okay.
Any tips would be helpful.
