Thanks gr5! I watched the video and tried your suggestion but I don't think its the K1 relay. When I set the UM2 to print, the red light for the build plate turns on while the nozzle light remains off. I tried tapping the PCB but it didn't change anything.
Also, I have no idea why but the build plate now heats up when I set it to print! I'll test to see if that stays consistent. All that's left is to get the nozzle to heat up as well!
Any other ideas though?
