Has anyone had the problem of hot-end power fet staying on all the time?
I already replaced the fet to see if it was broken and replaced the heater element to the hotend. Still not working...
There's only one resistor between the gate of the fet and the arduino output and I was wondering if the broken fet could have also damaged the arduino board?
I'll measure the whole RAMPS soon but I was just wondering if you guys have had similar issue before?
