Bearing clunk - but which bearing?
I dont consider my Vcore 3 to be very old, but I do wonder why sealed bearings fail, and how do we find which one?
If I push my toolhead diagonally, I can confirm the clunk is not from the linear rails (phew), since it only occurs in one diagonal, but I wonder if someone has a method to identify which bearing of that particular belt loop is the problem - I prefer not to dismantle it all.
And while I'm asking, why do these bearing fail at all - shouldn't they last for ages ( my belts are not overtight)...

Is this belt tension or something else?

Problem: the carriage could move with the motors ennergized, the lower belt pulley setscrew had untightned and pulley was partially loose...
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...
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
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?
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....
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.
