so i had my printer up and running, it worked got it calibrated etc. today i tried to get the hot bed to work, as i couldn't last time i tried. i set it to value 1 on marlin then verified and upoaded. it did not work apparently. i tried sswitching connections thinking it was in the wrong slot, ( a second extruder thermistor slot) but that didn't work and i switched it back. so i reverted it back to 0 value, now nothing is moving. the hotend stays on constant when i turn the printer on, and the temp on pronterface reads 150 for EX0 constantly. it says it's comunnicating, but nothing is moving. the motors are on, because i can't move them by hand. It's as if it's frozen in place.
i seriously need help
