IDEX offset but VAOC calibration was OK

Can you help me to understand why I get this X offset during IDEX print if the VAOC calibration was OK?

you need most likely a skew calibration

Helge Keck•2/22/25, 3:21 PM

after doing it you need to redo the vaoc calibration

alternativly you can align your gantry better to get rid of the need of the skew compensation

OK, I’ll try

I’ve tried but after a SET_SKEW CLEAR=1SET_SKEW CLEAR=1 I get AC=140,85 and BD=140,87 so I don’t think this is the issue

if you make a skew calibration, you need to tell ratos that oyu have a profile, then you need to redo the calibation VAOC calibration with the skew peofile

if this isnt the issue then its most likely belt tension issues

I’ve tried setting the skew calibration profile and redo the VAOC calibration. Then I tried to adjust the belts.
Here the tension charts before managing the belts:

And here after adjusting the belts (it was better before?) but I still have about -1mm of X offset on T1

@Helge Keck I don't kwow if it is the same issue fix-my-printIDEX XY Offset drift (VC4) but I've tried to send get_positionget_positioncommand after toolchanges printing this file
