VAOC Stuck on loading

Hi! I'm trying to get my RPI cam to work with VAOC, but always get stuck loading. The webcam itself works fine with the shown settings and "Adaptive MJPEG-Streamer", but not with WebRTC. Any ideas?...

Chonk needs coding for 3 axis Z-tilt

Hello guys I was hoping the Chonk builds could receive the option for z-tilt bed leveling. With a toolboard the skrat has the open slot. ZMA= Z0 E0M= Z1 E1M=Z2 just like a V-core. This would be nice to have. Is this possible?...

try adding

Moonraker Timelapse using wrong camera

Question, so I moved over to the built in moonraker timelapse setup in RatOS and even though I have my enclosure camera selected it keeps using the toolhead camera. I am running fluidd if it matters. Is this a RatOS issue or should I chase it down through the moonraker timelapse team. Not sure where the delineation of duties is 🙂 Thanks!

AWD Voron 2.4

I’m trying RatOS 2.1 RC3 on my Voron what do I have to add for sensorless homing in the printer cfg. Thanks.

weird new 'move out of range' after last update.....

heavily mod'ed 3.1 VC500 here... getting a negative Y value in a move out of range.. home all -> z_tilt -> warm up -> bed mesh -> then move to center front while hot end heats, then the very next move errors/freezes the machine with the statement
Move out or range: 25.000 -13.000 49.88
Move out or range: 25.000 -13.000 49.88
see pics here (under thumbnail in screen capture) mesh is 100/100 400/400 so its not Euclid probe offset numbers vs mesh limts at the edge of the bed....

My homing sequence seems to exclude the rear motor upon lifting to check the z.

I posted this in fix my printer but not many eyes there. This seems to be configuration related. When I first click home all three motors lower the bed. It then homes X and Y then Z goes to home only the two side motors lift and the rear stays. https://youtube.com/shorts/BwLV4EklHzw...
Solution:
Maybe a bad driver?

Realtime Analysis not loading and showing error.

I tried to get my VC4-300 IDEX running. Got the printer from Helge. Something seems to be off with the resonances. Tried to run the realtime analysis. it shows me an error, that somethine did not work, that's it. Tried to update the Configurator, did not work....

Raspberry Pi 5 not creating Hotspot

I've tried to follow the Guide on installing Rat OS for my new VC4 Idex but have nothing but issues with Rat OS. I was originally having issues with Balena Etcher not finishing the image on the SD Card since I was using a new buggy version of the software. Once I switched to 1.18 It completed the flash but when I install the SD card into the Raspberry pi 5 nothing happened. I waited an hour for the hotspot to start with no success. I reflashed the SD card to see if there was an undetected error when I flashed it. Then I tried to plug the Pi into Ethernet to see if I could connect it that way. I can not get access to the PI any way I try. Am I doing somthing wrong or is there somthing else that I can try? I've tried two different SD Cards, one from Microcenter and then I Ordered a SanDisk Ultra U1 A1 256gb and neither one works....
Solution:
PI 5 is not supported yet and probably won't be for some time so either you are on your own or you need to get PI 4.

Error updating RatOS: Git Command 'fetch origin --prune --progress' failed

First time I have run into an update failure.

Hard recovery fixed it

Rat OS VAOC Configuration

Kinematics config/dependencies

I keep getting flak for asking these things, but regardless; I would like to use RatOS, but always struggled with the interconnected web of dependencies in the config. My printer is a custom coreXY IDEX, but starting from a Vcore4 idex config. ...

Switching to performance mode -> z-tilt screws up

Upgraded to 3.1, toolhead and beacon With Mikkels help (thanks👍 ) I managed to set my three z-tilt probe points manually to suitable coordinates. After continuing with further commissioning and tuning, I finally came to the point where I switched to performance mode. I used the configurator to do that ( still not so familiar RatOS2.x). That completely screws up my z-tilt motion. Toolhead moves to weird positions and even bumps into limits - eg. in the front. So I tried a manual approach by adding to printer.cfg: ...
Solution:
this doesn't look like skipping, that looks like loose pulleys

x- and y-axis positioning incorrect after upgrading to RatOS v2.1-RC1

I just upgraded my vCore 300 printer from RatOS v2.0 to v2.1-rc1. After the upgrade the movement of the x- and y-axes are limited to the rear-left quadrant of the build plate. When I run a bed probe, only the left rear quadrant is scanned. If I send the extruder to x0y0 it moves to approximately x0y150. If I send the extruder to x300y0 it moves to approximately x150y150. The current printer.cfg is attached. The only changes I've made to the printer.cfg or any other setting is to change the...
Solution:
0.9 degrees, they need twice the steps generated, and there’s your quadrants 🙂

Change location of Prime BLOB

Can someone give me an example of the override lines in printer.cfg to change the location of Prime BLOB to the left (X=5 instead of x=395) position? It makes removing the blob easier because of the printer location in my print room. I've got a V-Core 3.1 400. TIA

Option 'endstop_pin' in section 'stepper_x' must be specified

Setting up my Chonk and I am trying to figure this out. I searched and nothing came up. I have sensorless homing selected in the configurator.
Solution:
Do you have a habit of just cutting power to your printer instead of shutting it down properly?

I don't see it anywhere but does ratos support rasberry pi 5?

I just purchased a 5
Solution:
not supported atm

How can I comment out Beacon surface scanner?

For some reason I can no longer connect to my Beacon Rev H mcu. I would like to comment this out for now so that I can test a new fan install but klipper will not do anything when it cannot connect to the Beacon mcu. Is it possible to temporally comment out the Beacon? I tried commenting out the [include RatOS/z-probe/beacon.cfg] in RatOS.cgf but it must be mentioned somewhere else also as I just get Unknown config object 'beacon'...

Custom Extruder Config in Overrides not recognized

I have a non standard Hotend and wanted to add a extruder section in the end of the file. Whenever i do this, my Sensor readout is wrong. When i put one of the standard includes into the printer config it works. Q: Builtin there is an extruder section in the printer.cfg from RatOS:...

unable to ssh in now!?!

I recently moved my printer to a different room in the house. I can access on web/mainsail but am unable to ssh into the pi. RatOS v2.0.2-36-g230929e3, klipper v0.12.0-229-g589bd64c, mainsail v2.12.0, Distro: RatOS v 2.0.2 (bullseye)...any idea why I'm all of the sudden unable to ssh in on Windows or Mac. Access denied I've changed nothing on the pi and have been ssh in for over a year...any suggestions on how to fix this?...

Probe points offset - unaffected by beacon x/y offset override

I just finished my 3.1 upgrade including a beacon probe. I'm currently running through the initial configuration. I noticed the 3 probe points used for z-tilt adjustment are shifted backward by several centimeters so that the probe point in the back is such that the beacon hangs halfway off the printbed. First, i checked my 0,0 point and that is where it needs to be. I didn't want to touch the kinematics variables since it's a stock V-core. So I added a beacon section to my user overrides in the printer.cfg: [beacon]...
Solution:
Yeah the default config assumes the default hardware on the default toolhead, which is/was a superpinda on EVA3 so the z_tilt points and positions and bed_mesh min/max is all tailored to the EVA offsets for superpinda. You should change those when swapping to beacon, unfortunately i currently don't have a great way to automatically adjust those as there's too much information missing....
