Extruder using wrong pin?
I'm running Marlin 2.1.1 on an MKS Base 1.4 board with Repetier Server/Host in the most current versions and have the following problem:
The second extruder doesn't heat up. After checking the wires (no defect), I realised that whenever I want to turn on Extruder 2, the fan goes on. And when I turn on either the extruder or the fan, in both cases D4 shines up, instead of D2 for the extruder and D4 for the fan. I assume this is a firmware problem with the second extruder being wrongly using the extruder fan's output pin. How can I correct this?
