Error gcode_macro _START_VAOC:gcode

Hello everyone, I'm new and I recently purchased my first RatRig v core 4 500. I apologize in advance if my problem is trivial but I don't know where to go to solve it. I followed the configuration steps from the manual but it continues to give me this error when I try to calibrate the VAOC: Error evaluating 'gcode_macro _START_VAOC:gcode': jinja2.exceptions.UndefinedError: 'extras.gcode_macro.GetStatusWrapper object' has no attribute 'z_offset_probe'....

Expansion ports pins not being copied to RatOS.cfg using wizard (EXP1_1 etc)

In the wizard I selected btt-octopus-11. It has pin aliases defined for the Expansion ports but they where not copied by the wizard to RatOS.cfg. I had to manual add them to get Expansion ports working for my LCD screen.

BTT Octopus Pro v1.1 with BTT Pi v1.2.1, Getting 502 Bad Gateway error

Greetings All, I have a SecKit CoreXY printer that I want to upgrade to use the RatRig ecosystem on a BTT Octopus Pro V1.1 (H723) and a BTT Pi V1.2.1. I'm using 32 GB SanDisk Ultra MicroSD HC1 in both boards. Everything is brand new and never used until now. (Also bought their accelerometer board.) A friend of mine is running his Voron on the same boards and software, though I'm not sure what version of RatOS he began with....

expected probe state to be deployed but is stowed (1) on start of print

Just added the klicky to my RR 3.1 500 and the klicky does everything fine. Z home, z tikt, bed mesh, stow and deploy. When I print I get the above error after the inital home and heating before print, extruder moves to do the pre print blob and the error comes. The probe is infact attached as this point. I would of expected it to detect before it does the blob and I think that is the error...

Solution:

Solved it. There is a bug in the adaptive mesh "[gcode_macro PROBE_FOR_PRIMING]" line 105 - "{% set z = printer.configfile.settings.bed_mesh.horizontal_move_z|float %}" where it doesn't account for the probe z offset. The config for my machine has a horizontal_move_z set to 5 and my probe offset is also about 5. For my fix I added "horizontal_move_z: 10" to the [bed_mesh] section (add section if not there)

No Klipper updates in months?

Hi, I realized I havent seen a klipper update and subsequent MCU firmware update, in many months. I had an update fail a few months ago where I had to manually update MCU firmwares and I havent seen a Klipper update since.

VAOC calibration problems andc huge .zip files in config

Hi, i have a problem with going out of calibration of VAOC and z offsets. When i home printer i click on VAOC and all is fine, setting up where the nozzle would be and everything, but when i want to go out of calibration or do calibration endstop it give me a error out of range like on the image. It was working yesterday, i put same values to ratos-variables.cfg but still have errors. I was trying with commisioning and other guides, printer is custom but no changes to RatOS, only in configuration, like i said calibration was working, i start to have problems after first attempt to copy mode (it wont work, in single mode its ok.)...

Non-critical MCU for beacon

Hello everybody, is it possible to set up the beacon probe as a non-critical mcu? I am having an issue with my beacon where it loses signal with klipper and kills my prints. I have tested multiple beacons probes and usb cables with no success which leads me to believe it is a power issue. I tried changing the powered USB hub as well as directly connecting the USB to the rpi but the issue persists. Being able to let the beacon not be critical after first layer would be really helpful. Thanks for any help you can offer 🙂 I unplugged the screen and the camera while running the beacon directly off the rpi power to see if there is any change, its currently printing but it normally stops a few hours in....

Can’t access ratos with ethernet connection aside from connecting to the pi WiFi.

Basically sums it up. I see you set the domain name when doing WiFi setup but it does not do that for Ethernet unless I am missing something. Maybe I skipped a step somewhere. I am not sure. Right now, I can only access the pi by using the built in RatOS WiFi. Then I can go to RatOS.local

Fan confusion

I have a vcore4-idex and while doing the testing of the hotend i realice that the T0 toolhead fan wasn't working after testing it with an external power source i realice it was unusable (maybe a fabric defect) i replace the fan but when doing the testing of the new fan i realice that when i test the T0 hotend the T0 toolhead fan should turn on but instead the controller fan turns on, and when the controller fan should be turn on (when rpi gets hot for example) the T0 toolhead fan turns instead....
