From day one, I had issues with the bed unleveling all the time even if I hadn’t touched it.

After watching more videos I bought springs and I was having fantastic prints every time. There was no need for levelling between prints - it worked perfectly.

The day before yesterday I got an error warning thermal runaway printer halted please reset so I did as the printer said and again tried the print and 20-30 mins in the exact same issue. I watched more YouTube videos and replaced the motherboard with an SKR E3 V2.0 mini with Marlin firmware installed on to it.

After installing I went ahead and tried to test print (file on provided micro SD card) and 30 mins in I got a thermal E1 so I went ahead and watched more YouTube videos which suggested that I connect my printer to my PC via a USB (provided) and download Pronterface. I followed the instruction of typing M303 V5 200 into the command prompt and sent it to the printer which again halted the printer with E1 error code. I went over to the printer and unplugged the USB and waited while the printer was off before plugged the USB back in.

After doing this I got a TMC CONNECTION ERROR message on the printer. I followed some Reddit/Github posts that said:

Send command M122 to the printer, this should work, which it did not.

As it stands at this moment this printer has gone from working perfectly to nothing at all.

    Please clarify your question:. "nothing at all" doesn't sound like "thermal runaway." – Perry Webb Jan 07 '21 at 15:03
  • It will print 1 or 2 layers then thermal runaway message comes up with a loud beeping noise – Mjlawson91 Jan 07 '21 at 15:16
  • So you replaced the controller board and experience the same thermal runaway behavior. That implies that the board isn't the cause. You need to check the rest of the hardware. Loose/faulty thermistor or heater cables, fan shifting onto the hotend, etc. – 0scar Jan 08 '21 at 12:02
  • I have corrected this issue by fully replacing the hot end and wiring (thermistor and heating cartridge) – Mjlawson91 Jan 08 '21 at 19:38
  • I’m guessing you don’t know then – Mjlawson91 Jan 11 '21 at 23:18
