Anyone have an idea why the laser would be cutting out sometimes? I’ve had it lose focus and then stop, other times it’s gotten a lot duller and stopped. It’s also not cutting very well.
I’m guessing an air assist should help the cutting a lot, I cleaned off a mirror and it helped, but a bit worried about the losing power. If I turn the laser switch off and let it continue with the job I can then turn the switch back on and it’ll work for a few more seconds…
I leave it for 1/2 an hour or so after it happening as I fiddle around on other stuff but it’s happening a lot more regularly now. I couldn’t even cut a 15cm line in 3mm plywood this afternoon. I have fresh water running through the laser. Doesn’t look to be any air bubbles.
EDIT: Just happened again, water cool going through it (lots of ice packs in bucket) the current is still up when it stops (12mA), that doesn’t change at all.
The manufacture date of the tube is 17 Sep 2013, so over 2 years old. Is that odd for a brand new machine?
