Dear RR Community and Mods,
I'm currently commissioning my VC4 and am running into a issue during the VAOC Z-Offset Step.
I followed the official commissioning guide (now multiple times) to the most minute detail.
18:32 _VAOC_END 18:32 RatOS | VAOC: Control point was set: X248.533610 Y529.435123 Z-1.740000 18:32 _VAOC_SET_TOOL 18:31 Error during homing move: Move out of range: 248.533 529.436 -7.000 [0.000] 18:31 Error during homing move: Move out of range: 248.533 529.436 -7.000 [0.000] 18:31 Error during homing move: Move out of range: 248.533 529.436 -7.000 [0.000] 18:31 Error during homing move: Move out of range: 248.533 529.436 -7.000 [0.000] 18:31 shaper_type_y:mzv shaper_freq_y:0.000 damping_ratio_y:0.100000 18:31 shaper_type_x:mzv shaper_freq_x:0.000 damping_ratio_x:0.100000 18:31 Activating extruder extruder 18:31 RatOS | IDEX: Toolhead offset applied for T0: X=-0.01339148516015598 Y=0.10378400999150017 Z=0.0 18:31 RatOS | IDEX: Selecting T0.. 18:31 RatOS | VAOC: Move T0 to control point: X211.032955 Y529.435782 Z-1.740000 IS_FIXED=True 18:31 RatOS | VAOC: T1 offset was set: X-0.013391 Y0.103784 Z0.000000 18:31 _VAOC_CALIBRATE_Z_OFFSET 18:31 RatOS | VAOC: Move toolhead: G1 X-0.137263 Y0.053566 F18000 18:31 _VAOC_MOVE X=-0.13726272289172384 Y=0.05356594064067271

or I get:

Error evaluating 'gcode_macro _VAOC_ENSURE_TOOLHEAD_WITHIN_CONTROL_POINT:gcode': gcode.CommandError: Unexpected y-coordinate detected, VAOC aborted. Expected 210.999 but got 248.499.

Please see attached for the Debug.zip

When trying to access the VAOC Calibration after a reboot I get: Error evaluating 'gcode_macro _VAOC_ENSURE_CONTROL_POINT_WITHIN_EXPECTED_CAMERA_POS:gcode': gcode.CommandError: VAOC x-control coordinate is set to 248.495 but is expected to be within 5mm of 211.056. Please run '_VAOC_RESET' to roll back to default values.

#

you havent made the dc endstop calibration correctly

#

please follow the instructions in the commissioning guide

#

this high x-offset s the reason why it doesnt work

#

the guide explicitly points oyu to that value to chaeck it

#

before this isnt fixed it wont work

no, this is yours, taken fro the debug zip flile

#

there is no doubt that this is your file

#

I see that - is it getting resetted by something possibly?

#

Because now it looks quite different..

#

well, i need of course the actual debig zip file, from your current state otherwise i cant help you

#

vaoc resets resets this values

static wave well, i need of course the actual debig zip file, from your current state otherw...

you got the one from like 10 minutes ago - anyway, heres the new variables:

#

now add this to your printer.cfg

position_min: -7```
