VOAC Z-Endstop calibration crashes into cam

After doing VOAC X/Y calibration. I exited and rentered VOAC. Started the Z-calibration and the printer moves up the toolhead T0 and then its moved down into the cam.

please include this file in your printer.cfg and add this underneath it

[gcode_macro _VAOC]
variable_is_fixed: True

[gcode_macro _VAOC]
variable_is_fixed: True

vaoc.cfg

then run _VAOC_RESET and try again its a new version with multiple fixes, not published yet but confirmed already that it works

PadOP•2mo ago

Just included it Mhh besides the fact that it moves Z way more now It still just moves up and down again I stopped it before it crashes into the cam a 2nd time

Helge Keck•2mo ago

please share your debug.zip

PadOP•2mo ago

Where do I get this

Helge Keck•2mo ago

in the ratos configurator in the navigation panel

before you clicked z-calibration, did you centered both nozzles over the camera?

PadOP•2mo ago

Yes I centered both toolheads Exited the calibration Started it again. Ensured both are centered and tried Z Calib

Helge Keck•2mo ago

try AGAIN WITH THIS ONE

vaoc.cfg

Helge Keck•2mo ago

didnt yelled, caps lock accidentaly active please recenter both nozzles

PadOP•2mo ago

Nope still the same behavior

Helge Keck•2mo ago

one sec so when its over the camera and you start z-calib, it just moves up and down? no sidewards moves?

PadOP•2mo ago

Yep

Helge Keck•2mo ago

do you start this with the left or with the right toolhead over the camera?

PadOP•2mo ago

T0 So the left one

Helge Keck•2mo ago

please share the ratos-variables.cfg file

please add this macro to your printer.cfg and then run TEST_VAOC in the console and share the console output

[gcode_macro TEST_VAOC]
gcode:
    # config
    {% set z_offset_probe_x_offset = printer["z_offset_probe"].x_offset|default(0)|float %}

    # ratos variables file
    {% set svv = printer.save_variables.variables %}

    # get reference point coordinates
    {% set idex_xcontrolpoint = svv.idex_xcontrolpoint|default(150)|float %}

    RATOS_ECHO PREFIX="TEST" MSG="idex_xcontrolpoint: {idex_xcontrolpoint}, z_offset_probe_x_offset: {z_offset_probe_x_offset}"

[gcode_macro TEST_VAOC]
gcode:
    # config
    {% set z_offset_probe_x_offset = printer["z_offset_probe"].x_offset|default(0)|float %}

    # ratos variables file
    {% set svv = printer.save_variables.variables %}

    # get reference point coordinates
    {% set idex_xcontrolpoint = svv.idex_xcontrolpoint|default(150)|float %}

    RATOS_ECHO PREFIX="TEST" MSG="idex_xcontrolpoint: {idex_xcontrolpoint}, z_offset_probe_x_offset: {z_offset_probe_x_offset}"

RatOS | TEST: idex_xcontrolpoint: 112.2784205187694, z_offset_probe_x_offset: 37.5

Helge Keck•2mo ago

please home your printer and move the toolhead to X150 and then tell me if its on the z-endstop x position or not thsi doesnt make any sense

PadOP•2mo ago

x150 is pretty centered on x/probe endstop

Helge Keck•2mo ago

wtf is going on here :kekw: give me a sec

PadOP•2mo ago

Helge Keck•2mo ago

please try this file, it moves up but not down, so it wont hit the camera. but please make a video of it

vaoc.cfg

PadOP•2mo ago

AFAIK this is also the correct odering to override the one from ratos?

Helge Keck•2mo ago

it is

PadOP•2mo ago

Just to confirm I do not need to have the E Stop close to me now as it should just move up?

Helge Keck•2mo ago

well, to be sure hover our finger over it :kekw: but i outcomment the actual probing move

PadOP•2mo ago

Umpfs seems like its working now and I just pussied out with my E Button after it crashed on the first try

PadOP•2mo ago

Vid is uploading

Helge Keck•2mo ago

sorry, i dont understand, you said its working now and in the same sentence you said its crashing a bit confused

PadOP•2mo ago

Sorry. It s working now. Just after my first try of running this calibration and the nozzle decided to crash into the cam (An hour ago) I was to quick on pressing the E.Stop for any of the other tries.

Helge Keck•2mo ago

ok, now try this file, but hover your finger over the button

vaoc.cfg

PadOP•2mo ago

Maybe it is better to move X/Y when the printer moved the bed down and before it moves up again to engage with the endstop. Makes it less scarry

Helge Keck•2mo ago

stop ok, just had to watch your video seems good now try the new file as described

PadOP•2mo ago

Its done now

Helge Keck•2mo ago

works now?

PadOP•2mo ago

High toolhead z-offset of 0.088125mm!

Your toolhead z-offset could be better.
Use minimum 0.3mm first layer height for copy and mirror mode prints.

Id say so

Helge Keck•2mo ago

ok, good to know, still weird why this change was needed for you and not for others kepp the file include until we published a fix

PadOP•2mo ago

Well maybe it was user error. As I mentioned I might have been to quick on the E-stop.

Helge Keck•2mo ago

no, this is something else

PadOP•2mo ago

Helge Keck•2mo ago

thanks for your cooperation :kekw:

PadOP•2mo ago

But still, I think it would be better to move to the endstop location before moving closer to the cam again Thanks for the help 🙂

Helge Keck•2mo ago

it does that before each print this way but when doing it manually we are jsut reusing other code that load the tool to the camera and then starting the z calib

PadOP•2mo ago

👍🏼

Helge Keck•2mo ago

remove include and update ratos
