Not able to upload STLs/3MFs to VC4 IDEX

Not even sure where to start with this one lol. The printer is built and working other than a few issues I need to figure out but the one that is effecting my ability the most to print is not being able to upload files over RatOS. When I try to upload the file ratOS tries to download the file but it fails every time I try. Ive tried all the normal stuff like restarting the machine and trying files that my vcore 3.1 has no issue completing the download. SO yeah! not sure what my issues is here lol...

Bed Heater Wiring Confusion

Hello, I am very confused about the wiring of the bed heater. My bed heater came precrimped with 2 straight male style connectors and a 2pin JST style connector. Photo attached. The photo I included from the wiring section shows 3 forks added to the wires on the bed heater. The instructions show connecting the fork style crimps to three locations on the power supply. The commissioning guide instructs the JST 2pin connector to be inserted on the motherboard. Could someone please clarify what is n...

Random Shutdowns with unknown cause

I'm getting Random Shutdowns with unknown cause. Not ever print does it happen. It will just stop and restart klipper and be in Idle status with a clear command line. Snipit below of just when it happens. Temps look fine and noting stands out to me although I've no idea what half of this means. You can see it is at print time 534675.933 then the next line is starting Klippy! ...

Can Anyone ID this noise?

Happens when homing any axis before movement. Movement /printing otherwise sounds ok? Perhaps it’s normal - just trying to get things setup for the first time after buying this second hand....

Error when trying to running calibration on VAOC camera, "no attribute Z_Offset_probe"

Solution:
[z_offset_probe] pin: ^PG10 # probe trigger pin z_offset: -7 # probe height, used to limit the probe z-move y_offset: 0 # probe y-offset, measured from the camera centre x_offset: 37.5 # probe x-offset, measured from the camera centre...

random MCU disconnects on 24 hour prints. klippy log interpretation wanted.

I have attached my klippy log. I suspect it’s my usb cable as this is generally the issue, but wondered if someone with more knowledge of the system could interpret my klippy log and see if there was another underlying issue. I have wanted like 9kg of filament in failed prints over the last week. The issue seems intermittent but tends to happen after 12 hours of running ...

VAOC not streaming

So the camera works as it should in RatOS through crowsnest. I can activate the camera in the webcam tab but in the VAOC tab I just get a "Stream not found" error when I click on it. Did I miss a step in the configurator or something? Almost seems like the VAOC isn't part of the config.
Any guidance would be greatly appreciated....

Ratos Configuator update gets stuck at 91% -93%

I am trying to commission my Vcore4 and when I try to update ratos configuator it will not complete and gets tuck at 93%. When I refresh the update will complete and everything else updates ok. Then when I try to flash my board in DFU the board isn't detected. I have tried 3 Pi's, 4 new SD cards and 2O Octopus v1.1 boards all with the same result. I have also tried to flash it with a SD card with the compiled firmware and I still get board not detected. Any help with this would be very much appr...

G28 Internal Error On new Install

So having a similar issue with a fresh install using 2.02. At first I struggled with my SKR2 459 board firmware not matching even though I compiled new and loaded. This eventually got worked out in Kilpper and no more errors showing (though it still shows the issue running in the configure setup wizard). When I home or even move the head I get the "internal error on command G28". However if I use the "Set center kinematic position" I was able to home and run a print no issues. But after it just went back to same problem and error. Any ideas what may be going on? I attached, printer.cfg, klippylog and Debug but not sure exactly how to grab that one so just zipped a txt file.
Thanks...

Finish the Commissioning guide

I tried to change into the performance mode, but I can't save the changes. I think it is because both toolheads have warnings ...

Then you should be fine

VORON IMPLEMENTATION ISSUE - BEACON CALIBRATE

Just completed my 2.4 upgrade to beacon/orbitor2/rapido2UHF to match my RatRigs currently operating. During initial Beacon Calibrate it will not QGL because the values keep increaing like the motors are not assigned correctly. I have looked @ the wiring too many times to count, verified ratos.cfg assignments, verified ratos config wizard selections. Octopus Pro 446, EBB42, PI4b, Kind of at a loss now, any insight????

Stepper X not moving

So I am a little mind blown at this point, When homing, my stepper x does not move. IDEX 400 VC4, dual carriage stepper seems to be moving fine, but when homing or doing anything, stepper X seems like its doesnt even have power. I have tried a new octopus pro 1.1, new 5160T pro drivers in all slots, and a new stepper motor. I don't even know what to look for now. hoping its something on the config side that im just overlooking but havent been able to find anything that stands out. When homing Y,...
Solution:
Was bad octopro, and some how the 1st new octopro was also bad :facepalm:

Error: An unexpected error occurred during post-processing

Vcore 3.1 500 IDEX. Was working fine before updating ratos. seems trivial, hopefully it is. I'm using an orangePi board. I know... but it is working fine. until now. I just updated my ratos (it has been a while). I re-sliced a file and now I'm getting this error in the logs. I'm unable to print any files. all have this exdev error. ...
Solution:
I FIXED IT. It appears to be a bug in how the postprocessor tries to rename a file using node.js, which can't be on a different device (ie ramdisk). I modified the TMPDIR environment variable for this function to point to a tmp directory on the sdcard for the process_gcode_file function in ratos.py. This way the function works as it should since the files are on the same device. See below: I created
/home/pi/printer_data/gcodes/tmp
/home/pi/printer_data/gcodes/tmp
Then I edited ratos.py located at
/home/pi/ratos-configurator/configuration/klippy/ratos.py
/home/pi/ratos-configurator/configuration/klippy/ratos.py
under the function
def process_gcode_file
def process_gcode_file
I modified with the following ```...

Offset between walls and solid infill

Hello, I do have a massive problem with my printer. Its an IDEX500 And I have a difference between T0 and T1. 1. When printing with T1, I got massive waves of resonance within the print. But this is only to the extrusion, not due to wrong input shaping. It seems like the extruder has a resonance, not the toolhead. 2. I get an offset between walls and solid infill while printing with T1 only. the comparison between the gcode preview what the printer thinks its printing and the actual print is attached. If the printer is printing in copy or mirror mode, there is no offset between walls and the solid infill. ...
Solution:
Problems solved! The reason for the offset between the walls and the infill was broken raspberry PI.it seems like that the raspberry gave wrong comments to the main board for the second print head, the first print head absolutely fine but the second didn’t. I can’t explain why this happened but after switching to another PI 4B the problem was gone. This leads to the conclusion that the raspberry PI could lead to such issues.

Issue with belt tension graphs

Hey everyone, I'm building a V-Core 4 IDEX (currently CoreXY). Everything looked fine until I started testing belt tension. No matter what I do, the upper belt always has more tension than the lower one. At some point, the gantry became tilted and now it can’t reach the Y-axis endstop. Any ideas on how to fix this?

Core V4 500 IDEX - commisioning - first print failed

After posting on FB i ask my question here and added the debug.zip I want to print the skew_correcton.stl from the guide, my first print I use Prusa slicer and imnported the setting as pointed out in the guide. At first after doing home and Z-tilt the printer made a big blob on the oozeguard_arms. After a good look in the config there was a ! added to the extruder pins. I removed that. Now the blob is put on the print bed, then the print head moves above the oozeguard_arms and retracts the filament, it keeps doeing that saying 'extruder allready active' in the console. What can this be? Thank you in advance!...
