Idex, parking not in the center
I assembled v-core 4 idex 300, after parking in the home position the print head is not in the center of the table, on the Y axis it is also not in the center, when calibrating VAOC it is possible to bring the head to the camera only with the parameter position_max: 450.000 in stepper_y, also when calibrating T1 an out of range error appears on the X axis

Can you share RatOs-debug.zip?
despite not having to do with X home position, why do you have this?
[stepper_y]
position_max: 450.000
and you are missing the margin variables. Probably it is messing your homing position
I sugest doing this
https://docs.ratrig.com/v-core-4-0/idex-commissioning#vaoccalibration
from "Initial vaoc calibration" until step 13
because with a smaller value of position_max the head T0 does not reach the VAOC camera and I get an out of range error, I cannot complete the VAOC calibration because the head T1 when moving along X does not reach the VAOC camera and falls into an out of range error
after repeating VAOC calibration and CALCULATE_DC_ENDSTOP several times I was able to complete the VAOC calibration but now T1 parks like this

after I changed position_max: 400 for [stepper x] the heads started to park in the center, is this normal?

but with this configuration the print area is 450 x 450 in the printer configuration
Will this configuration work correctly when printing from a slicer?
this is the last debug with this configuration
You have a 300 machine. Either 400 or 450 is plane wrong…
The parking position 436… is wrong.
Y max 450 is wrong.
Camera y position 416 is wrong
Position endstop and position max for DC is wrong.
Are you sure your machine is 300?
If so, restart configurator from scratch and discard everything else.
The “extra” value over bed size for any axis should be max of 60
I reinstalled ratos completely, updated all packages as stated in this manual https://os.ratrig.com/docs/installation/
Then launched Setup Wizard and configured all steps for v4 idex 300
Then added settings for VAOC and camera operation according to this manual https://docs.ratrig.com/v-core-4-0/idex-commissioning
Then I executed _VAOC_RESET and M84 and launched VAOC calibration and got these physical head positions after the error: Move out of range: 111.659 334.284 5.000 [0.000]
Installing RatOS | RatOS
This is preliminary documentation for the upcoming v2.1.0 release. The work is still ongoing and the documentation is not yet complete.


parking in the home position remained also not in the center of the table
maybe there is something wrong with the settings for the stepper motors?

It is completely impossible to be anything on settings. Hundreds of machines runing RatOs 2.1 and to mu knowledge this is the first time a Vc4 has this.
I will look at the files again.
Probably your out of range is on Z because both X and Y are inside the limits.
try this:
open your printer.cfg and set Y position_max: 335
save_and restart
Follow the instructions on VC4 commissioning from "Initial vaoc calibration"
Unfortunately it doesn't work 🥺
I found the problem, apparently by mistake they sent me Timing Pulley 16 Tooth
🫣
I apologize for my inattention
oh my! That would do it! 😛
WFT!!!! We could have been on this for months 😛
