Extruder Driver 1 Won't turn a motor

MakeStuffMakeStuff

I'm having some issues with my Duet Wifi. I've added a second extruder, and for whatever reason the second extruder driver motor won't turn. It is a brand new Bondtech LGX if that makes any difference. Maybe someone can take a look at my config and tell me what I'm missing?

You map first the axis and after that you configure the drivers move the M584 command to line 18

Unfortunately that isn't the problem. I tried it just to be sure, but it didn't change anything.

Side note, if I swap the extruder cables for E0 and E1, I can get both of them to run, however the motor running on E1 seems weak. Potentially a driver issue? That would be weird though as this driver was used successfully for quite a long time as a Y axis motor driver due to motor cable length problems.

@makestuffmakestuff A few things to note.

When you map extruders using M584 like you have here...........

M584 X0 Y1 Z5:6:7 C2 E3:4:8:9

.....then whichever motor you have connected to E3 will become extruder 0, and whichever motor you have mapped to E4 will become extruder 1, etc.

So your first tool definition....

M563 P0 S"Hotend1" D0 H1

.........will use extruder D0 which is the one connected defined as E3.

Your second tool definition......

M563 P1 S"Hotend2" D2 H2

.....will use extruder number 2 as defined in your M584, this would be whatever is connected to E8.

So if you only have 2 extruders, then the second tool definition should be

M563 P1 S"Hotend2" D1 H2  (not D2)

One other little thing. You ought really define the micro stepping for both extruders in M350 using a colon separator so instead of....

 M350 X16 Y16 Z16 E16 I1

...use .....

 M350 X16 Y16 Z16 E16:16 I1

It probably defaults to 16 so it might not matter but it's generally best practice to explicitly define these things.

This was exactly the problem. I knew it was going to be something simple like that, I just stared at the problem long enough that I couldn't see it. Thanks for your help!
