Heatbed Resistance
I'm looking for some help. My MK3 has not functioned since I received it. The problem is that it either resets or turns off completely when preheating. I contacted support and they felt it was a problem with the heatbed. They had me measure the resistance of the heatbed which was 2.9 to 3.0 ohms. They stated that was too low and should be 4 ohms and sent me a new bed. The new bed is the exact same resistance and did not change the problem. I feel that it is most likely a problem with the power supply which seems to be underpowered for the printer. I also noticed there is a thread on here for power supply problems that is around 20 pages long. Would any of you mind measuring your heatbed resistance so I can comfirm what the correct resistance should be? Thank you for your assistance.
