Bad stepper motor?

Started having issues with the straight lines essentially turning into gyroid😂 I believe I tracked it down the the T0's stepper motor having a very mechanical hard to turn spot that I could feel moving the print head, after taking it apart it is in the stepper motor itself for the hard to turn spot then it frees up and repeat. I've never dealt with stepper motors going bad much is this something that looks like it could cause this? In the pictures the White is T0 and the darker is T1 and yes i...

VAOC IDEX Calibration toolhead collision.

I'm commissioning the first-time IDEX 500 and trying to configure VAOC based on the guide, but I'm colliding with the tool head every time I try to calibrate it. Any help would be appreciated.

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....

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. ...
