I am having an issue not sure how to correct it, have a 900w 12 ps, a heater that works (tested it by hooking it up direct) the board reports the temp rise, pronterface shows it, but still get no voltage on d8, have metered both sides of the fuse and both read 12.3 v, but the board just will not turn on the heater, no led comes on either, i see the led but it does not come on like the one for the extruder, the printer works fine for pla, but i have 12 kg of abs i cant use because the heatbed issue, any ideas..
