See....the printer has only one hotend (extruder)(two extruder motors feeding one hotend(extruder)). The problem here is that, the hotend (extruder) no longer heats up. When I unplugged it and connect it to a 24v supply, it becomes hot but when you put it back on the board and u turn on the pre ...

No. The printer uses one extruder. Its a 2 in 1 config. (Two extruder motor feeding one hotend). The present hotend port is not functioning. I need the hex firmware to activate another hotend together with its corresponding temperature sensor port. Thanks a lot.

My present extruder port stopped working. I feel since there is additional 2 extruder ports, I can still use any of them.
Kindly send firmware to enable me use other hotend extruder ports Thank you.
