VOAC calculating offset wrong by the same amount every time
Well I read the new commissioning guide and when I went through the gantry check it was out on the right side by 3mm! So I have a badly skewed gantry. Prints great like that lol. Anyway I corrected the issue by loosening up the screws on the x gantry plates to the Y carriages, and also loosened up both Y linear rails and re-aligned everything. Now I have it all back together and the gantry is perfect in the back and front. Going through IS now and when that's good I will do the initial setup for VAOC over again and then check if the offset is correct. Report back when done.

What is the offset compared to? Obviously the IDEX_XOFFSET is not the actual distance between toolheads. The VAOC routine moves the toolheads a specified distance and then compares where the nozzles are relative to that? So for whatever reason I'm guessing that relative distance is about .75mm different than what the software calculates. If the T1 endstop was out of position by .75mm along the X axis, the software would have the toolhead in a different place in X than it actually is relative to an assumed X max. I am not sure how you keep the endstop location out of play here. Granted that doesn't mean you don't keep it out of play, I am just not sure how you do it.

Double checked configurator I have it set for a .4mm nozzle which I am using on both toolheads.

How far off would I have to be to be creating a 0.9mm difference?

Yes I have this exactly matching. It has to be something else.

Yes I started doing that as well. I just find it interesting that the software is doing that. It seems like a bug. But maybe not, you can fill a lot of libraries with stuff I don't know lol At any rate maybe it's related to my issue.

Ah pixels/mm. But I am lining up the the nozzle diameter really closely. Hard to believe I am almost 1mm out. I do the calibration until it repeats perfectly. I do notice that sometimes when I drag the nozzle in the image, it doesn't move completely in terms of the amount I move it. It does at first but repeated moves without changing from t0 to t1 or vice versa result in ever smaller movements relative to how much I drag it. Almost like there's a buildup of error, perhaps in the software?

How does the VOAC calculate offset? I am guessing it is using the x endstops? Problem with that is there a ton of tolerances involved that can build up in the wrong way.

I fixed it temporarily by altering the idex_xoffset in the ratos-variable.cfg.

I ended up doing it via ssh as I didn't want to configure a wireless network. Thanks again

Z-Axis Crash during homing after tall prints
Interesting, I will have to just remember after printing a tall print to use center kinematic position and lower Z enough to avoid the horrible noise

Z-Axis Crash during homing after tall prints
But logically if you had an endstop at Z max and was triggered that's a physical signal that "Hey stop increasing Z now stupid printer" lol
