502 Bad Gateway

Dear all, I'm struggeling with an "502 Bad Gateway" error since I've updated the whole RatOs after configuration, when I'm trying to open "Configurator", "Realtime Analysis" and "VAOC". It just shows a "white page" with the error. Anyone any idea, what I'm doing wrong? Thank you so much, Volker...

Solution:

no worries. Try SSHing into the raspi and run ratos doctor

Sample spread always too large

I keep getting this error. I have checked all possible causes multiple times, tightened all screws several times, and inspected everything. When the pressure plate is cold, everything works fine, but as soon as it starts heating up, I always get this error. I've been trying to solve it for three days without success.

Second EBB42 toolboard: Not able to setup.

Hi, I´m running into an issue with getting a second EBB42 toolboard installed. I had to buy a new one because I ripped off the USB socket of this board by accident. Can someone please help me with that issue???...

Solution:

Well tried that first but with no luck... Tried the manual way as in the past before using RatOS... and failed too. I now used the configurator once again setting again to IDEX and chose fresh install. Now it worked as expected and the second EBB42 is recognized: ``` pi@ratos:~ $ ls /dev/serial/by-id/*...

Error during accelerometer data streaming - lis2dw

I picked up a used V-Minion the other day and have been trying to get it up and running. I've added a BTT S2DW board under the bed. I'm able to get Klipper communicating with the sensor over USB, however I'm not seeing anywhere in RatOS to specify anything being there being a connection to the host; Nothing specifying the actual sensor type outside of Klipper .cfg files. ...

Increasing bed mesh points?

Hey guys i'm wondering if there is a way in the printer.cfg file to increase the number of probed points. I'm currently using the super pinda probe and it appears to probe 7x7 or 49 points. I guess im wondering if I could say double that somewhere? Thanks again guys Chris...

mcu pin name vs board pin name

Trying to utilize one of the four 24V heater block connections labeled HE0 - HE4 on the BTT Octopus V1.1 board to power the LED bars I received with my V4 kit. For no particular reason I conected first to the HE3 block and set up my "LED" text Identifying the "white" pin as PB11 per the BTT pinout. Klipper provided an immediate "No LED pin defined" that I eventually troubleshooted by finding the text "e_heater_pin=PA2" in the RatOS.cfg. I moved my wiring to HE0 and redefined the LED pin as "P...

MCU shutdown: 'Timer too close' at the end of VAOC Calibrate Z-Offsets

I went in an mcu shutdown timer too close during the z-offsets calibration process in the VAOC. This is repeatable. The probeing procedures completed for both toolheads, but at the very end when the offset between the toolheads is calculating it fails and the printer run in a mcu shutdown, quickly. It looks like the pi is too busy, but i think specially at this point the calculating of the offset is not a very complex (a simple subtraction?). The printer is in stock configuration except a usb webcam and two BTT sfs v2 filament sensors. It is a VC4 500 Idex machine....

toolboard device conflict

I'm trying to configure my printer for a pico-mmu, where I have an EBB42 on the toolhead (vc3.1) and another for the mmu. They're both coming up as t0. I tried following the instructions at https://github.com/lhndo/LH-Stinger/wiki/Pico-MMU-RatOS but my situation was different, in that both of my toolboards had already been flashed as t0 at some point (the one now on the MMU was originally on the toolhead as I was assembling it, but the USB broke off and has since been repaired). I've tried USB flashing just the 2nd one (they both appear as t0 in the configurator), I've tried USB flashing both the first and second board,...

Change Wifi SSID without configurator

Hello everyone, is there a way to change the wifi ssid (same password, just a different ssid on 2.4 GHz instead of 5 GHz) without having to go through the configurator again? Thank you in advance!

Solution:

I believe you can just run through the configurator for just that step and save, but if you don't want to try that you can edit the wpa_supplicant file manually

[VC3.1-400][ratos 2.1.0-RC2] Do I have to restart from scratch?

Yesterday I put the 2.1.0-RC2 ratos installer on my Pi and followed the setup instructions. I successfully got the Pi to connect to my WiFi network. Next, the Pi successfully detected my Octopus and flashed the firmware onto it. After that the webclient asked me to choose my Extruder, Thermistor, Fan, etc. which I did. So I believe I am now at the step where I go to the Update Manager and update the RatOS package. But there is no RatOS entry in my Update Manager. As you can probably tell I am not really a software guy and this is my first time working with a Pi. At this point is it safe for me to connect all my steppers, fans, etc. to my Octopus? How do I know if I have made any mistakes so far?...

Filament runout detection pausing at start of sprint

I'm running a Mellow Filguard Filament detector. Like the title says it's pausing the print at the start of a print. When I extrude a bit of filament I see the sensor and jam sensor both turn to "detected". But if I don't do this they are initially marked as empty and when the print starts they are still empty and it pauses the print. pressing resume won't help in that case I have to disable the sensors for the print to actually start and continue. I set it up on my config in the following way:...
