Purchased a Cohesion3D board about 2 months ago, replaced the nano board that came with the laser.
Yesterday powered the machine up and everything was normal, except it wouldn’t home, move or respond to lightburn. Looking in the machine I only see one red light on the 3D board, there are usually several flickering.
I pressed the reset button but no change. I powered everything off and back on but no change.
It appears that the board has failed, or I need some more troubleshooting.
