Board: Cohesion3D LaserBoard
Firmware: Latest Smoothie
Problem/ Question: The issue came up about 2 weeks ago: the board started to disconnect only when engraving (about 5 minutes after start). Then started to disconnect also when cutting and now it disconnects in the first second after starting a job. I didn’t change nothing in the wire connection, and it worked perfectly in the last year. I have noticed that the LPSU makes some weird sounds when cutting (like a click but high pitched) Could this mean I need a new LPSU? Any ideas?
