After selecting any project, controller screen becomes sluggish to advance steps (but will back up without hesitation). When finally able to set material thickness and project origin, job starts then head raises to top position and screen shows project paused. 5-10 minutes later controller will accept resume input. Head will move into position and project will pretend to run for approximately 4 seconds before pausing again. I say pretends to run as laser does not power on.
Attempted with: attempted with fire sensor on and off; door detection on and with it off. Removed and replaced all cables; cable pins in good shape, cleaned with ISO and dried.
I feel the fan may be the right path. Received similar guidance on the help ticket that was opened. The reason this feels like the likely cause despite no error messages, as I opened the case to check the connection and ensure the fan rotated freely, I was granted with what looked like melted plastic bits everywhere. I’m at a loss where it came from as this has been an issue from the first day I attempted to use it straight from the box (yeah, yeah likely story…dingus probably did something stupid)
Scraped off heat exchanger and fan and dumped out the burnt smelling bits. Tested door contacts and sensors independently and they are lighting and appear to be functioning well. Next is the hook up and test.
If you are lasering composite woods, like MDF or Ply, the melted resin can clog the laser and fan..
I recommend an air intake and tubing. plans in Thingiverse.
