4028 fan does not stop completely

Because my original 4028 died some days ago, I installed a spare ARCTIC S4028-15K fan and connecte d the PWM to the toolboard as normally. Now... I can set the speed as expected, but the fan does not stop completely. The fan is turning really slow but it´s turning even in Fluidd/Mainsail it´s set to 0. Any idea how to fix this issue?...

RatOS homing behavior

Hi guys, I recently swapped to RatOS, just wanted to ask what the homing behavior is supposed to look like, since when I homed last night, the probe was left hanging out of bed in the front left corner and the bed crashed like hell 😅
Solution:
thanks for the suggestions! Turns out sensorless homing was off a little, so sometimes it homed correctly other times not as much, so it was acting wonky.

Move exceeds maximum extrusion (2.673mm^2 vs 0.640mm^2)

Trying to print some basic stuff and getting the following message: Move exceeds maximum extrusion (2.673mm^2 vs 0.640mm^2). Nozzle in slicer is 0.4 as well as in RatOS.cfg file. The print stops during prime blob, so i think it is not related to sliced file. Any help are more then welcome...

RatOS 2.0 upgraded to v2.1.x - Custom V-Core 3.1 with Etched Foil bed heater w/ 3 combined sensors.

Hi everyone, I'm running a modded V-Core 3.1 AWD that was working great on RatOS 2.0. But after upgrading to 2.1.0-RC2-106-g8614d79, my custom bed heater setup stopped working because of a conflict with an existing parameter. The Etched Foil heater has double thermistors (named as "bottom_x") and the 12mm alumium plate has another one in the top. As the whole bed system/ arms are metal I am able to heat the heater to 180C (on the bottom) without problems, so that allows me to get the desired temperature in the top much faster than usual (usually 105C). ...

I'm confused about which version of RatOS to download.

I have the RatRig V-Core 4.0 kit with the OEM Raspberry PI 4 board. Which version do I download off of GitHub?

Beacon Rev H - Will not pass calibration. What is wrong?

Doing the configuration. Everything starts out fine.. passes then gets to the last part... throughout when it is outputing latencies, it is 1-3... all of a sudden at the end.. its now 4,5,6. It is doing the final sampling (from right top corner).. I get sample readings that are ridiculous.. I have went and checked the z rod couplers... if I am reading it right, I push them down and tighten to the stepper motor shaft... and there needs to be a space between the stepper shaft and the bottom of...

RatOs.cfg issu

Heyy i have the problem that if i change my ratos.cfg save an restart the canges are right If i turn the printer off and power new than the canges are gone. Did anyone know why?...
Solution:
The ratos.cfg gets regenerated after every restart. Overrides belong in the printer.cfg

Outdated Beacon firmware

Can't get input shaper setup 'Option 'accel_chip' is not valid in section 'resonance_tester''

I have a USB input shaper that has Klipper flashed (and works fine on my other printer) that I'm trying to get working as a secondary MCU. I have included the same cfg file as what I used on another printer perfectly fine, and am including it in my printer.cfg on the RR. The configuration file looks like this: ``` [mcu PIS] Obtain definition by "ls -l /dev/serial/by-id/" then unplug to verify serial: /dev/serial/by-id/usb-Klipper_rp2040_E6635C469F178338-if00...

RatOS-v2.1.0-RC2 How do I set configuration that is not included in the "Configurator"?

I just upgraded to the latest pre-release. I went through the Configurator. I have a handful of configurations I need to set. Things like neopixel, beacon y offset, adding additional temperature sensors, additional fan control, fan kick start time, etc. I'm wondering, what is the prescribed method for these things? I'd happily read the docs if they exist; it seems like the os.ratrig.com/docs is mainly 2.0? I realize this is a pre-release; I'm just trying to be self-sufficient and would gladly read the docs if they exist....

Can not update MCU 'mcu' error after updating

This is a new Vcore4 build. I've put RatOS 2.1 on the SD card in the raspberry pi, and gone through the initial configuration. The MCU and toolboard flash correctly and everything looks good. When I open Mainsail, there were a couple orange errors. I unfortunately did not document these but they had to do with a T0 range error. I browsed to the machine tab and update RatOS, then did a full update. After the update I get the MCU update error in the title. If I browse back to the configurator, it...

V Core-4 IDEX Klipper shutdown when trying to generate input shaper Graphs on toolhead 0

Hello, I have a problem with my custom build v-Core 4 IDEX. As soon as I start generate shaper graphs or measure core xy belt tension macros on the first toolhead (0), Klipper switches off. On the second print head everything runs without problems. The first print head is equipped with the Beacon sensor, the second with the ADXL from the Ebb toolboard.
Solution:
It's trying to use adxl345 beacon which is not a thing. Have you updated everything and/or did you add that yourself?

Supported board but unsupported printer

In the process of updating my V-Minion and was going to replace my old skr mini e3 v2 with a RatOS supported board. Both the M4P and Mini E3 V3 are supported, I'm guessing they are for the experimental Prusa support, but they are not supported boards for the V-Minion - https://os.ratrig.com/docs/printers/v-minion. They have more than enough ports, even more when using a tool head board. What's the best way to use one of those boards with the minion, or an unsupported board in ratos like the Pico...

mellow board support

I made a file to support mellow super 8 pro. I just don’t know how to do pull requests. I can share files but just don’t know how to process it. Also I want to make two mellow tool boards compatible too but that’s for later
