The bed seems to have given up and I can't find the answer anywhere.
After I applied insulation to the bottom of my MK2 and ran it a few times it would not go above 90C. I thought I knackered it so bought a brand new MK2a but it made no difference. After reading online I though it might have been a bad polyfuse that can't reset itself, so I shortened it out, but again no cigar. I also noticed that the heatbed mosfet gets very hot (might be normal) so I stuck a heat sink on it anyway but I'm pretty sure 0 difference was made.
Don't know what else to check, please help.
RAMPS 1.4 - Marlin - PID is off
PSU 12.20V when bed off. 11.5V when on
V to bed 10.6V
