IDEX VAOC Alignment problem - dual color

VC4 400 IDEX just finished commissioning. Ran a dual color calibration cube and the 2 parts are off, primarily on the X axis, by approx 0.75 to 0.8mm. 0.4 nozzle, so any small off-center in these particular images is a small fraction of 0.4mm. T1 is printing a full 2 nozzle widths to the left.

The VAOC commissioning guide has been followed, and VAOC calibration done numerous times. CALCULATE_DC_ENDSTOP output has been copied to Printer.cfg and done more than once in hopes that it would work. I now have 4 identical cubes that look like this. Green is T0, Grey is T1. T1 is always laying down 0.8mm to the left side.

X stepper set screws are tight, belts are not slipping from the CNC belt clips. No loose screws that I can find.

Really at a loss. I see Helge Keck is no longer here, but I sure hope someone can assist. IDEX is the entire reason I bought and built this machine.

DC Endstop output:
[dual_carriage]
position_max: 459.560
position_endstop: 459.560

variable_bed_margin_x: [59.800, 59.560]

[gcode_macro T1]
variable_parking_position: 457.560

Note that I left in the prior values for the DC Endpoint, commented out in printer.cfg, for reference. Parts printed identically.

Any assistance would be welcome! And thanks in advance.
