[BUG] IDEX - DUAL_X_CARRIAGE_MODE in FULL_CONTROL does not manage hotend X offset properly

[fcza]

Did you test the latest bugfix-2.0.x code?

No, but I will test it now!

Bug Description

I have been using IDEX DUAL_X_CARRIAGE_MODE in "DXC_AUTO_PARK_MODE" for a while. In this mode, i calibrate the X hotend offset in marlin LCD (advanced menu). This works OK.

I now need to use IDEX DUAL_X_CARRIAGE_MODE in "FULL_CONTROL" to manage tool change routine using custom instructions (gcode) in my slicer. HOWEVER, i find it impossible to apply a working HOTEND X offset so that both hotend are well calibrated on X.

Bug Timeline

not sure

Expected behavior

I expect the HOTEND X OFFSET setting in the Marlin Advanced menu to tune heads X alignement in IDEX FULL CONTROL MODE, like it does very well in AUTO_PARK_MODE

Actual behavior

in IDEX FULL CONTROL MODE, Prints from each head are not aligned. Modifying the x offset seems to have no effects.

Steps to Reproduce

Use IDEX DUAL_X_CARRIAGE_MODE in "DXC_AUTO_PARK_MODE". (OK)
Calibrate Hotend X offset based on trial and error measures on dual head prints - untill perfect (OK)

Switch to "M605 S0"

Execute print with custom "on tool change" instruction to home the old tool...
RESULT: prints from both IDEX head do not lineup (around 2mm in my case) ==> ISSUE
Trying to calibrate X offset (marlin advanced menu) does not change the result ==> ISSUE
