VAOC issue (x offset on T0) after last RatOS update
I made some VAOC calibrations this morning, then I saw a RatOS update (2 commits) and updated. Then I tried again with VAOC but the toolhead 0 isn’t centered but has and offset.

please enable the debug mode, clean the console output, then reproduce one single time, then share the console output
ahhh, can you please make aa test for me
can you outcomment your skew correction in the printer.cfg and try again
I don’t know if it is related, but if I try Calibrate Z-Offset I get this error too:
thats expected bc of the same issue
please make the test
can you include this file in your printer.cfg and then redo the test please
I had a collision with the right Y motor
when did this happen?
please share your printer.cfg
During the camera approaching
so when both toolheads are trying to move back?
I think T1 doesn’t move on X axis before moving Y axis, I’ll try again with the finger ready on Emergy stop button
restart klipper and jsut click START_VAOC without homeing manually before
OK
so this is your y control point in VAOC
and thsi is in your ratos.cfg
please add this to your printer.cfg
I’ve added it (and removed the vaoc_test.cfg because I had another collision) but I still have this offset
when you have the collsions
so you are saying that not both toolheads go over the build palte when starting VAOC?
or does this happen when the toolheads are already in the back
Yes, I recorded the previous collision (the IP cam have a delay) and I forgot the "Emergency stop" button isn’t available during VAOC 😭
you can have two windows open, one wiht mainsail and the other with vaoc
please move both toolehads over the build plate and then home your printer
just want to make sure T1 still works
Yes, the last test commenting the include vaoc_test.cfg worked but there is still the issue on T0 offset
OHHHH
i think i see the issue
one sec
to confirm, please run
_VAOC in the console and share the output
i believe RatOS thinks you have a non fixed VAOC device isntead of a fixed one12:11

_VAOC
weird
ohhh, one sec
please include this file in the printer.cfg, clean your console output and start vaoc. it wont move back, so no crahs will happen, but it will print some data to the console. so i need the output
wait
please put this after the file include
my bad, sorry
no woder it did that
The toolheads moves in center of the plate
nice, now its safe to use this one here and to repeat the test
sorry again for that
but keep this of course after the include
do not remove it
Still having the offset issue
Don’t worry, thanks for your help
can you outcomment your skew correction and redo the test please
It worked 🥳
now enable the skew correction and try with this one here
Works with skew correction enabled too
yeehaw
ok, can you make 2 more tests for me
try to start a z-calibration, but hover your finger over the emergency stop button :kekw:
and the same for temp offset calibration, you dont need to wait for the actual compensation, just want to know if the toolhead moves to the endstop pin
then you can restart klipper
how can I slowdown all the movements? 😱
in the mainsail ui you can set it to 10%
there is a speed slider somewhere
The Z-Calibration movements are as usual when I calibrate, but after it, I get a spinning button of Z-Calibration
ok, but the toolhead hits the z-endstop button, right?
Yes
ok, thats all i wanted to know
looks like this is sovled, thanks for your help
if you encounter any other issues with it please tag me
keep the new include until we publish a fix, i will notify you
OK, thanks, I try the temp offset now
actually no need
but test it
It worked (I had to retry because T1 dripped a little during expansion at 250°C)
well, when doing the temperautre calibration you should unlad the filament with a cold pull and clean the nozzle
as described in the documentation
but good to see that it works
I made a cold pull this morning, but not enough I think
by hand?
No, using something like this:
COLD_PULL EXTRUSION_TEMP=230 COLD_PULL_TEMP=85 TOOLHEAD=1
On T0 with PETG and higer temperaturer was fine. On T1 with a matte and fragile PLA I think something is left in the extruder

remove include and update ratos
