Laser Engraver Forum

I think I've isolated this issue to electrical interference from other equipment operating in the shop. Switching to a higher quality power supply appears to have solved it.

New laser owner, Sculpfun 20W diode. Working on my first project, and about a dozen pieces in a started seeing an occasional missing horizontal line, as though the laser is not powering for that pass. What is the cause/how do I fix this issue? Picture attached.

Thanks!
