I’ve up graded to the NEJE E40 mkII laser on my NEJE 3 plus. But the laser is not turning on when I start the job. Bizarrely if I do a ‘Frame’ command, the laser actually turns on an engraves the frame, but the laser doesn’t turn on at all when asked to start the job (although it obviously does move the module laser around to complete the job).
Does the E402 need the external 12V?
