Automatic restart if MCU is detected

Since I turn off my printer once in a while and keep the RPi running it would be convenient to detect the MCU connection via USB and trigger an firmware-restart. I searched with the klipper context and found the following USB rule that I adapted to look for my MCU: in /etc/udev/rules.d/98-klipper.rules I use: SUBSYSTEM=="usb", ATTRS{idVendor}=="1d50", ATTRS{idProduct}=="614e", ACTION=="add", RUN+="/bin/sh -c '/bin/echo FIRMWARE-RESTART > /tmp/printer'"...

Read-out extruder stepper motor commands

Hi all, For or application I want to write an extra Pythonscript in klipper for communication with our dispenser. The main problem we have is that we want to read out in the curruntly writen code when the stepper motor for the extruder should be activated at what speed. If we can find that and read that out at the beginning of our script than we can transfer that data and use the GPIO pins of our Pi to activate our syringe. Does anyone now how to arrange this? ...

Problem with long RasPi camera cable

Ive been having trrouble with my camera - I want to use the camera port because as I understand it, it can use hardware to avoid too much CPU load. The trouble is, to have the camera at the front corner where I want it, it would seem a long cable is my problem - with same settings and short cable I can get the video feed, however with the longer cable needed for the corner location, I cant get an image using same settings. After days of frustration, changing settings etc., some research identitifd that long acbles have too much line loss. Funny thing is that is was working fine for months, then stopped. Maybe the FFC was damaged where is goes through the cover, so I replaced the cable. Does anyone know a solution/workaround?...

RatOS 2 and Rasp Pi v3 cam

Is there anyway to get this camera working with Ratos 2? I have tried several guides with no luck. Fresh install of Ratos, tried a reload of crowsnest. Only getting "no signal". Camer is detected "/base/soc/i2c0mux/i2c@1/imx708@1a" any help?

not seeing Octopus Max for a control board in printer setup. Ratos V2.0.2

changing wifi setting in raspberry pi.

hi all, i posted this in the klipper discord, but haven't heard anything yet. hello all, i recently had to factory reset my router. i put in the same ssid and pw settings but i lost my pi. i checked the ratos-wpa-supplicant on the sd card, but it does have the right ssid and pw. ALTHOUGH pw is # in front of it and below it has another psk that is not #, and it has a very long alpha numeric string ( maybe 50 characters ). So question is, is there a solution in the wpa supplicant, or will i...
Solution:
I fixed my issue. turns out for some reason my router was producing 2 ssid's that had the same name at 2.4 no other device could detect these 2 ssid's but somehow the raspberry pi could. i created a guest 2.4 ssid and connected it to that using the ratos.local/configure and it finally connected.

prevent pi4 hdmi shutdown while printing

Well, really I'd like to prevent it from going into power save mode/screen blanking in general, but mostly during prints. I tried following the directions in http://raspberrypi.stackexchange.com/questions/47229/ddg#100347 though now it's an all black screen instead of powered off, so there must be something else that I'm missing....

Klipper screen and web gui are different

ratrig V3.1 500 for probe chose.

Hello. Do you think I can use the sensor whose product link I gave below for my Ratrig v3.1 500 printer? Can you give me information about this? "https://www.leuze.com/tr-tr/is-108-mm2nc-4n0-m83/50129919"
Solution:
@mavi - ilezirabbit Save yourself the headaches (and the waste of money) and buy the recommended probes. If you prefer mechanical probes that touch the bed, look at euclid (it's a stowable probe, so requires a dock on the frame and some initial positioning calibration). If not, my recommendation is Beacon, priority number 2 would be a Superpinda (sold by multiple vendors, RR sells them in their shop)....

Wrong hotend temperature

Hi all, I just finished building my VCORE 3.1 300mm standard kit (no modifications). When I'm on ratos.local, the hotend temperature is at 159°C but it should be the room temperature and when I give a target (for exemple 200°C) the temperature decrease and I get an error. I searched on ratrig docs but can't find my answer, can you help me please ?
Solution:
Sorry, I found the solution, I added sensor_type: PT1000 in the [extruder] section of printer.cfg and it works 🙂

remote access/port forwarding

This is more of a general networking question, but I am not familiar with port forwarding, and I would like to get to a point where I can remotely access ratos without having a computer on the same network (printer is in a warehouse, and I can access ratos remotely) I have gotten around this by putting a computer at the warehouse, but ideally I would like to be able to get rid of the computer and do everything remotely. Is this possible by port forwarding the IP address the raspberry pi is connected to, and connecting to moonraker using a public ip/port?...

raspberry pi camera module 3

Hi, will the Raspberry Pi camera module 3 work with the latest Rat OS without custom scripts? I want something with autofocus.

Part Fan not working as it should

I have and EBB42 but I connected my 4pin OWM fan to the board and not the toolboard. I did not enable in printer.cfg FANS section any fan., but had made my entries in override. Now I see the fans as in image put the slider for the fan does not control the part fan. if i use M106 P2 S255 from console the slider will move to the 100 & on the monitor but the part fan still does not move. If I do a print the fan wil turn on but at 100% and always on. What is wrong I have in connected as in the ima...

possible Z stepper issue?

I just want to rule out I'm not doing something stupid with my config that could lead to anything that would induce the issues seen in my other post. https://discord.com/channels/582187371529764864/1201626937748111512...

Fresh RatOS install x2 and still can't get the MCU to respond

Have installed RatOS x2 today, Have a brand new Octopus V1.1 flashed via sd card, and tried flashing it through RatOS a few times and the Configurator keeps telling me Octopus V1.1 Detected but is unresponsive. Not sure what else to do other than do the whole thing through SSH like usual.
Solution:
Ok.... I finally got it to work.... Reinstalled RatOS on the Pi another 2 times in the last 24 minutes and now its detecting the board.... @miklschmidt Maybe an Idea, Nothing more. Post a note on the OS install page for users not using an SD card that the install might not work properly and to try reinstalling RatOS a couple times before pulling hair out. Like me 😁...

Changing WiFi

Hopefully a simple solution, recently changed the WiFi and need to set RatOS back up. Quickest way just changing the image on the raspberry pi or do I need to set everyone back up from scratch?

endstop z still triggered after retract

Hello, just got through most of the errors in klipper for my first rat rig but this error has stumped me. So when I go to home all basically x and y work just fine (using eb42 v1.2 toolboard) for x endstop. But when it tries to home z it crashes into the bed. I have the super pinda probe and have attached my printer config below. Thanks everyone for your help!!!!!!
Solution:
change line 284 to pin: ^toolboard:probe_pin # For NPN NC probes such as the Super Pinda / Vinda / SupCR / Decoprobe probes....

Brand new and having klipper errors. I have attached the printerconfig.

I am using a ebb42 toolboard and for some reason get a heat error. It seems as though the firmware wants to pull thermistor temp from MCU and not toolboard.

variable_adaptive_mesh fault with Bl-Touch

Hello. I want to use the "variable_adaptive_mesh" setting. I have a vcore v3.1 500 encloser printer and it has BL-Touch on it. The accuracy result of my BL-Touch is as follows: "probe accuracy results: maximum 1.860625, minimum 1.787187, range 0.073438, average 1.824437, median 1.825000, standard deviation 0.024391" I organized all my files. I leave my cfg file below, you can check it out. When I start printing, after making the adaptive mesh, I get this error when printing starts and I couldn't find the reason for it. Can you help me? ...
Solution:
I was using a BL-Touch clone. I replaced it with micro-probe and my problem was solved.

Changed position BLTouch

Hi all, I changed the position of my BLTouch, where can I program the new location so that the bedleveling and bedmesh are still the same as before? Thanks!...
