Now that I know what to expect, I would not be caught by this. That does not mean I won't run into something else...

@deckingman said in 3rd extruder issues:

E4:5:6:7:8:9

That worked. I know I was overlooking something simple, in this case, the "D" parameter being logical and not physical. Thank you

I have the Duet Wifi and a DUEX5 board. I am attempting to configure 3 extruders. At the moment, I only have one heater connected, as I am trying to get the extruders working correctly. i will work on the heaters after I have the extruders working. As such, I have set all extruders to use heater 0. I also have not set my offsets yet, as they have yet to be determined.

I have a Cartesian printer, with dual independent Z axes, connected to the Z and E0 connectors on the Duet Wifi. I am using E1, E2, and E3 for the extruders, numbered Tool 0, Tool 1, and Tool 2

The issue I am running into is as follows: Tools 0 and 1 work perfectly. Tool 2 will not turn. It just vibrates back and forth.

I have verified my wiring, repeatedly. If I remap E3 on the DUEX5 to Tool 0 or Tool 1 in the firmware, making no wiring changes, the motor connected to E3 on the Duex5 works perfectly. If I remap E1 (on the Duet Wifi) or E2 (On the DUEX5) to be Tool 2, the problem moves to that connector.

This suggests to me that I am missing something in the configuration, but I am unable to determine what it is. Knowing me, it is probably something simple that I have overlooked.

This is my config.g file, minus the network section:

G90 ; Send absolute coordinates...
M83 ; ...but relative extruder moves
M555 P2 ; Set firmware compatibility to look like Marlin
