Looks like the thermistor is bad. Which is annoying at best. Luckily its a fairly easy fix to get going again. I’ve only been running this bed for 4 months though. Doesn’t scream longevity.
Don’t expect a refund. Those guys at QU-BD sent me a bad one. Ignored my emails for a month while I was asking for help or an rga#. When I finally got the rga# I shipped it back the next day. That was months ago. Still no refund.
That’s when I got the one from alirubber. no problems with that one.
I figured as much. They were nice enough to start a support ticket for me so well see. I have a 400w 24v power supply coming from open builds so I can use the one from alirubber.
