Hello. I’m running GRBL software on a Universal Laser Engraver machine (not the best, I know), and Mac OS X 11.2.3. Everything was running OK yesterday (months with no issues, actually), and today after the Mac OS X update it still worked. But then Lightburn got stuck on “Busy”. The console says “Port opened, waiting for response.”
I updated LightBurn and it hasn’t corrected the issue. Tried unplugging the laser for 10 minutes to stop the data transfer but as soon as I plug it back in I get the “whirring” noise. I don’t even touch the software and it starts acting up again. Can I go back to an older version of LightBurn? What else would fix this issue?
