The 3d printer i used to print the mpcnc has to be sent back as its faulty so im going to try and print my new 3d printer using the mpcnc so…
I am trying to add an extruder and hotend to a duel endstop configured mpcnc, ive used aux 1 to breakout the pins to a board with a stepper driver for another extruder as discussed here but no pins.h or anywhere to set the pins for the extra extruder?
I have also set the thermistor connected to T0 so i can now read the temp of the hotend (connected to d10) but when i try to heat it up i get a min temp error even tho the temp is reading about 20 degrees (in marlin the min temp is set to 5)?
I have fixed the heating error somehow the heater was reading 1 ohm resistance instead of 3.9 and removing my harness and connecting it directly has fixed it so there mist have been a slight short in the harness causing it to fail heating.
Im still looking for how to set the pinouts for the extruder to use the outputs on aux1 instead of the normal extruder outputs as obv they are used for x and y… what should i search for in config.h
ive sorted the min temp error it was because the heater was shorting slightly! Sorry im using ramps 1.4 and im trying to add another extruder motor using aux1 (is this the correct method?) the link i posted says i must change pins.h to assign the correct pins to the correct extruder motor?
You will need to change E0 the the right pins (new pins) I think I set them all to 70. The file will be pins_ramps.h (90% sure) and marlin 1 it is in the main folder, marlin 2 it is marlin/src/pins/.
I have never added an external driver so I can not be sure the correct pins. Yeah Aux 2 and 3 look to have a few open pins.
