A bit of a backstory. I’ve got a spinal injury so a bit mobility limited. Had my K40 for a few months, it was working great until it wasn’t. Has had maybe 20 hours total use over 6 months.
First it would stop the beam randomly during jobs. It was at different spots and during different files.
I replaced the laser tube as it’s winter here and I worried a rare cold overnight snap while I was hospitalised had somehow broken the tube, new tube is aligned and focused. Intermittent power down of tube persisted.
Thought perhaps the door switch or safety switch were an issue so jumpered them out. Problem persisted and laser beam progressed and stopped all together. Test switch and PSU TEXT fire correctly and register well on the analog mA meter.
Replaced pot (waited a month for shipping). Test switch works, head moves for job, beam doesn’t fire. New pot is very pretty though!
It’s the old style k40 with the analog meter and Nano board.
I’ve a programming background and electronics aren’t my forte. I’ve also tried k40 Whisperer on a Raspberry Pi and my Mac in case it was software related. I have a multimeter for diagnosis but no real idea how it works
My thoughts are - psu? (Replacing that scares me.) Control board failing? Grounding issue (I’m in Australia and we do have a grounding pin in the power plug, and I can’t reach the little ground wire in the back to sand the powder coating so it’s still how it came new)? Something else I’ve missed?
Has anyone got any advice for this poor stressed out chick please? The laser is my hobby and has kept me sane while I go through treatment, not having it is hard smiles
Thank you in advance
