Start up: power/light switch does not work, switch laser on laser homes and is ready but ammeter reads 20 amps and power switch/light now works. Ammeter reads 20 amp but reduces to normal when cutting.
I have had to replace the LSP and purchased stock K40 replacement. All wiring is as original but now power on switch only works once laser is activated and this turns on laser beam and power switch now works.The laser works but does not stop after cutting and remains on continuously. Any suggestions please.
Thanks for reply. I have now sorted power switch problem so this is what still happens:
Turn on laser, lightburn connects and laser homes but laser is on running at 20MA. Can run job at normal laser settings OK but current returns to 20MA and laser stays on.
your question 3:yes
your question 4: connected with pwm lead from mini gerbel controller as photo.![IMG_0060|375x500]

First thank you for your response. In desperation and knowing that all wiring was exactly as original connections I removed the mini gerbil board and replaced original M2 Nano board. Works perfectly so was obviously a fault with the gerbil mini board.
Sorry to have taken up your time.
