Burned or Bricked raspberry 4b - no 3.3v

Hi, im setting up my custom printer and i want to use RatOS for idex mode. Setup: Kraken v1.0 rpi 4b / 3b+ 2x ebb42 orginal vaoc camera ect...

Fan Confusion

I have a vcore4-idex and while doing the testing of the hotend i realice that the T0 toolhead fan wasn't working after testing it with an external power source i realice it was unusable (maybe a fabric defect) i replace the fan but when doing the testing of the new fan i realice that when i test the T0 hotend the T0 toolhead fan should turn on but instead the controller fan turns on, and when the controller fan should be turn on (when rpi gets hot for example) the T0 toolhead fan turns instead....

moonraker not connecting

For the past few days, I've been losing connection to the pi. Today I tried doing updates and it only seems worse. Here's the error im getting and the log. In the log, im seeing this: Failed to detect local IP address

Replacing my 24V heatcore but mistakenly ordered a 12v one

Would the 12v heatcore cause any issues? Will I have to hook it up on a different slot to step down to 12v? or will the current slot autodetect the voltage from 24v to 12v?

Cooling 4028 fan 12v won't run.

I have tried and measured everything..No movement to be had. cycle time, 0.0004, 001, 01, voltage measured at the toolhead, blue cable of the fan connected to white and in the correct plug holder on the EBB42 board, the connection jumper on the EZ MAX board is on 12V. Anyone have any advice?

VC4 full kit: unable to read tmc uart 'stepper_z' register ifcnt

Finished building my VC4 500 hybrid today using the preconfigured kit. Flashing and all worked fine. Followed the entire commissioning guide to the point of homing the printer. Get the unable to read tmc uart 'stepper_z' register ifcnt error every time while trying to home. So far tried: Reseating /swapping drivers, checking VBUS, reflashing control board and the Pi, checking all jumpers and entire wiring. Board: BTT Octopus V1.1 F447 Drivers: BTT TMC2209 V1.3...

Chamber Temperature Display?

I want to add a temperature sensor so I can heat my chamber to a certain temp before printing. I also want to add an exhaust fan to keep my chamber at a set temperature while printing to prevent jamming in the extruder. I found a little info on the ratos website but I can’t understand how I need to add the code to the cfg file. Also what pins I should use for the temperature sensor and the exhaust fan? I can’t seem to find any info in the discord.

Z-Offset / Beacon Compensation / RatOS V4 500 IDEX

I originally had the issue that, during calibration, a Z-offset of around 0.138 mm was always set automatically, no matter what I did. In order to address this, I took the following steps: • I heat-soaked the printer for 1.5 hours with the nozzle at 150 °C (approximately 20 mm above the heated bed) and the bed at 110 °C, • Deleted the existing Beacon model,...

Flashing Octopus Board V1.1 & RatOS

I am struggling to flash an octopus board for my V-Core V3. I tried flashing it with a microSD card because the dfu was not detecting the octopus board. I tried removing all the jumpers and just connecting the board to flash it and many more but it doesn't seem to work. I use RatOS v.2 and I'll attach the screenshots from there. Also I was worried that the cable was not a data cable so I used the same cable for the working V-Core we have in the Lab. It didn't change anything either....

Issues Flashing EBB42 v1.2 via DFU

In the initial setup I got all my boards flashed just fine. After the full printer was assembled the main board needed new firmware flashed fine. But now I cannot get the EBB42 v1.2 to flash using DFU as automatic is disabled. Every time I hit the buttons in the corresponding order it doesn’t seem to do anything.

Unsolveable version mismatch after reinstall 2.0 vs 2.1?

I started doing some long overdue updates 2.0, in the logs it said a reflash of the mcu might be required after the updates. Indeed there seemed to be a problem since nothing of klipper worked anymore afterwards and neither did automatically/manually flashing it... So i did a complete reinstall of rpi and clean setup. I got the version mismatch during setup (see picture) and reflashing it does not solve it. I decided to ignore it and continue, everything also seemed to work until i try to home it initially. I get an error that the axis should be homed before homing?? (see picture) Setting center kinematic position and everything works fine afterwards. ...

Gantry Twist & Bed Mesh Issues on RatRig V-Core 4 500

Hey everyone, I'm running into some issues with my V-Core 4 500 and could use some advice. I'm dealing with gantry twist and bed mesh inconsistencies, which are affecting my first-layer quality. On the assembly phase, we did use a water level to align the 3030 extrusions, but the result is always incorrect according to the sensor. Has anyone else dealt with this on a V-Core 4 500? Any tips or guides to adjust the frame? ...

Bed moving down by home command.

Hello, I have a problem with initializing the V-Core 4 Hybrid. I have all stepper motors working in the right direction. The bed I can move up and down with the arrows after the M1 command. But when I restart and click on the orange "HOME", all X and Y movements go correctly, but the bed keeps going down, without stopping.

Issue with VCore 4 IDEX 500 Homing – Carriage Crashing into Frame

Hey everyone, I recently got a RatRig VCore 4 IDEX 500 and ran into an issue during the homing/calibration process. Even though the endstops appear to be working properly, the dual carriages keep crashing into the frame when homing. It seems like something’s misconfigured, and I’m worried it might cause damage. I’ve attached my configuration files and some videos showing exactly what’s happening. If anyone has experienced this or can help troubleshoot, I’d really appreciate your input. ...

Hello I have a wierd sound on my Ratrig v-chonk and also a wierd Input shaper graph. Anyone have an idea ?

BEACON_INITIAL_CALIBRATION Issue

Hello, I put together a Vcore4 400 Idex and am going through the commissioning guide. The first issue that I've run into that I can't seem to figure out is when running the initial beacon calibration - where after I run BEACON_INITIAL_CALIBRATION, the X and Y axis home for the tool heads, then T0 moves to the center of the build plate and then the Z axis slowly raises up. When the build plate gets close to the beacon sensor, the indicator light on the sensor turns red and the bed keeps moving, crashing into the nozzle so I have to E-stop. My questions are: What does success look like for BEACON_INITIAL_CALIBRATION? How do I know that it completed successfully? ...

Printing paused or how to disable clog detection

Hello everyone, I'm currently trying to print the skew_calibration but am already failing to do so. When I start the printing it pauses randomly, sometimes after a few lines or right after the prime blob. I recognized that the sensor flashes yellow briefly before changing to green and then pausing. When I force him to continue he unloads the filament. I enabled debug and it seems to be the clog detection. I tried to disable it in the printer config. but it has no effect. Did I do something wrong or is there any other possibility do disable it....

VC4-500 Idex weird first layer problems

I have been chasing this issue for many hours at this point and while many things have improved there is still something weird going on. The skirt potion of every print that I try, and parts of the initial perimeters do not adhere to the build plate at all. I think it is because of the z-offset but I am not sure. After that point, the rest of the first layer is laid down beautifully. Even with all the blobs from the failed portion of the print in the way....
Solution:
Well, I have made a silly mistake - installed the 0.6 nozzles instead of the 0.4 as didn't realize the printer came with both. After switching tha tover was able to quickly dial tihngs in as expected 🤦‍♂️

Extruder Temperature Destabilization

Hello, I have run into a bit of an issue. During printing, the temperature starts to fluctuate, eventually exceeding the verification range, and erroring out. When I simply set the extruder to the same temperature, it holds it rock solid (+/- 0.5C), even with the fan on. Here is my override, as I have the rapido 2.0 non-PT1000. -----------------------OVERRIDE---------------------- [extruder]...

Status LEDs not changing color

I have installed neopixels in the corners of my V-Core 4 and the leds are not changing color when I use the machine. The sample code did not control the LEDs at all until I changed the `[neopixel nozzle_led_t0] pin: toolboard_t0:PB0 chain_count: 4...
