Correct config.g for 1 extruder with 3 heaters
-
Hello All,
I'm a newbie, technical background, but new to electronics and code. I am struggling to set up a high-output extruder which has 1 stepper drive and 3 heaters along the length of the nozzle. The Duet2 has a breakout board which drives X, Y, and Z. I plugged 2 of the heaters into E0 and E1 heater terminal blocks and 2 Dyze high-temp sensors into E0 and E1 VSSA thermistors. I have attempted to add an adafruit max31865 to the board temp daughterboard to run the 3rd sensor. I'm not quite sure where to plug the 3rd heater into. I have plugged an external stepper driver (Rtelligent R60) into Drive 4, and the extruder stepper motor into it. On the 2 heaters plugged in I'm getting very low readings, jumping from 2 degrees to 13.8 degrees. The heaters to not follow heat commands from the controller, and the extruder stepper doesn't either. Follows is my config.g, any help/suggestions/criticism would be much appreciated
