IDEX layer shift
So just finished the bulk of the IDEX upgrade on my VC4 300 - everything looks ok. Configurator re-ran to update to IDEX, I have control of both print heads, etc. Went to print the VAOC parts and while the first layer goes down fine things seem to drift after that. It's almost like it loses track of where it is. Any suggestions? You can see in the attached image the second layer is offset by about 15mm X & Y.

check belt tension, and listen for any stepper skipping noises. This is a print using only T0 right?
Only T0, haven't heard any skipping noises at all but will recheck belt tension.
Not great at all but shouldn't be skipping like crazy - I'll work on tension a bit:
With it moving diagonally like that, I'd suspect an issue with one of the motors. Double check the pulley is tightned onto a flat on the stepper shaft
I have had a grub screw let loose before - I'll double check it that it's locked down.
T0 belt stepper is locked down on the flat so it's not that. Trying to work belt tension now.
gotta check all steppers
I'm going through them one by one right now
The other X stepper is for T1 so that'll be last - but T0 X, plus hybrid Y motors.
