My CR10-S5 with Creality v2.2 mainboard recently suffered from the hotend heater transistor (MOSFET) failing short. After taking a look at the board, I tried to be clever and use the
HEATER1 output instead for my hotend. However, after swapping pins in
pins_RAMPS.h, there is no response to turning on the heater. I have confirmed zero volts on the board output with a multimeter, so it shouldn't be a failed heater cartridge.
Are there any other lines of code I should be changing to get this to work? I am using TH3D Unified 2 firmware with BLTouch enabled.
