Layer shift multicolor idex
Hey everyone,
I’ve got a V-Core 4 (500 mm, IDEX) and I’ve been going through the full commissioning guide. All calibrations check out ok— motion system, squareness, tramming, belts, etc. Everything prints good in single-extruder mode.
The only issue I’m hitting is when I try multi-color printing with IDEX: I get a layer shift in the X direction.
Single-extruder prints or IDEX copy is good.
As soon as I switch to multi-color = consistent X shift.
Both extruders are aligned and calibrated according to the guide.
Also did the gantry skew and die VAOC according to the guide twice.
Thanks in advance 🙏

If you print in idex mode you need to do the VAOC calibration every time before the print. There is a good chance that there still will be a small offset. I personally have a small offset every time, but haven't fully calibrated my printer yet. Your issue is not uncommon
Thanks. Yes this is exactly what I did. _VAOC_REST and then calibarion of VAOC before evrey print but none ever had good X layers.
Y is absolutely perfect.
