U axis and G3...Error:Intermediate Position outside machine...

[FBG]

Duet3 HC and Duet 3 6XD. all version are in 3.5.1

I am working in a IDEX printer that have in the same gantry X axis and U axis, T0 and T1.
If i work with "Arcs commands" G2/G3 everything is perfect if i use T0 and the gcode you can read X command...
But the same file, working with T1 and of course the gcode have U letter instead of X letter, Console give me and error

Error: G3: Intermediate Position outside machine limits

If i disable "arcs commands" all work perfectly of course.
Is like the U axis don't support arc G2 and G3

Any idea?
Best Regards

@FBG As far as I know, no, you can't use G2/G3 with a U parameter for a U axis, only XYZ. Is your IDEX using U, rather than mapping U to X, which is the more normal way to set up an IDEX? See M563 X parameter: https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_IDEX#configuring-tools
