Gcode On the Duet3 Behaving Unpredictably

DukeMachine

I'm working on a DIY embroidery machine and I'm using a Duet3 6HC as a controller for the machine.

I've setup inkstitch to use the following stitch command:

G1 X%X Y%Y
M98 P"trigger3.g"

Where M98 P"trigger3.g" is:

G1 U5 F1500
G1 H1 U500 F1500
G92 U0

What I'm experiencing is very odd. I generate one file, and the machine moves normally. I generate another file, the gcode looks very similar, but the machine only moves in the Y axis. I've attached two of the gcode files in question.

V13 works as expected, V26 does not
TextTestV13.gcode TextTest26.gcode

I'm not really sure if this is a problem on the Duet side or the Inkstitch side.

I note that the V26 files starts with negative X axis moves ( although they both contain negative X axis moves at some points.

By the look of this Inkstitch expects the machine 0,0 position to be in the center of the work area. Is that how you have the machine setup?

Also as an aside inkstich is inserting an M30 at the end of the file which is often program end in CNC gcode, but in 3d printing gcode its a file delete command (for historical reasons). Please try

please post your config.g
