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 (thanksđź‘Ť ) 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....

Error when trying to use VAOC

Error evaluating 'gcode_macro _START_VAOC:gcode': gcode.CommandError: VAOC safe_z value too low!

Im trying to use realtime analysis but im getting an error when i want to display the graph

Here is the debug
Solution:
Aah.. two different accelerometers that runs slightly different sample rates.

MCU or T0 or T1 running at the wrong Mhz

I've gotten a shutdown and error every time I try to print. Not sure what is going on. I haven't changed anything since I completed a print with no problem, last night.

Print Start Preheat extruder to 150c

So before I start a print, I will usually manually preheat my extruder and bed to 240c/80c just to get everything up to temp for 30 minutes. When I actually start my print, ratos will "preheat extruder" to 150c but actually it's waiting for my extruder to cool down to 150c before later reheating to 240c again. Is there a way to change the "preheat extruder" to 240c instead of default 150c? Thanks
Solution:
but if you really want to do that at full temp you can set the ratos variable preheat_extruder_temp to 240

RatOS doesn't want to update

Installation guide says to update RatOS first, then click on update all components, but my RatOS tab says invalid and offers me soft recovery and hard recovery. When I press soft recovery, it spits out error that it didn't get all the packages and I need to do the hard recovery. When I do hard recovery it says done but nothing's changed. Any help?
Solution:
it just says that the first time until it gets internet access and can update, Mainsail decided to show "invalid" there for some reason and it causes this confusion

Error evaluating 'gcode_macro START_PRINT:gcode': gcode.CommandError: Something went wrong! Missing

Hello I get this error: Error evaluating 'gcode_macro START_PRINT:gcode': gcode.CommandError: Something went wrong! Missing Already tried the fix which is in the Forum but I didn't have the code which would be the problem. I also tried this: https://github.com/HelgeKeck/RatOS/blob/documentation_v2.1/site/docs/slicers.md#prusa-slicer And tried to with pruas and orca slicer....
Solution:
please update ratos and try again

shutdown: ADC out of range - I think I found out why, but I can't figure out a permanent fix

I received this error at first start up, fumbled around the internet for data on the thermistor and toolboard (EBB42 V1.2), and found that the default pull-up resistor value is set to 2200 ohm when it should be set to 4700 ohm. At least, I am fairly confident of this because it worked in getting the temperature sensor to read correctly. The issue now is that the value doesn't stay in the RatOS.cfg file. It seems to revert back to 2200 ohm if the Rpi reboots. I can (and do) just go in and change...

Where do you put the wifi login for a rasberry pi 4b with 2.1?

I just got a rasberry pi for my chonk and can't find the folder to put my wifi login. I have done this with the CB1 on another printer with no issue but this time it doesn't seem so smooth. I first used balena etcher and I saw a wifi section but never saw it on my wifi. I just reflashed it with raberry imager and now I dont see a wifi section in the text folders

separate LED circuits?

Is it possible to add 2 separate LED circuits to the Octopus pro? I have the chamber lights on the RGB port but want to add another separate set of ARGB LEDs to control separately to the chamber LEDs.

Rat Os crashes when trying to print large file (440mb)

I'm tring to print a large print, i';m not sure if this is a limitation of my hardware (manta m8p) or ratos the file is roughly 2kgs of filament, 400mm tall (its a bust) it takes an age to slice and upload, but when i go to print nothing happens
Solution:
@James if you update RatOS it will now skip postprocessing if there's not enough memory available on the system to process the file.
