Massive Layer shift after 2 hours
Starting last week I've started having significant issues with the X axis of T0 on my V-Core 4 500mm IDEX printer.
I'm getting a huge layer shift and it's very clear that the toolhead is no longer properly homed after a couple of hours mid-print. After cancelling the print, and it going to the park location, it's no longer on the ooze guard.
I heard a grinding sound coming from the carriage rail bearing for T0 several days ago. I disassembled the toolhead to see if there was something in there. I've cleaned the rail, and it seems to move ok, but I'm still concerned that there's a bearing issue. Could that be responsible here?
Otherwise I'm at a loss. Suggestions welcome.

OK after some inspection, it seems there's a misaligned bearing on the lower left rear belt that's wearing the belt and I think periodically gets bound enough to stop the motor
so it'll require some disassembly to fix
At least it is easier to do that on the VC4! Good luck
Ah it's not the bearing alignment
Looks like it's the belt itself
I just removed it entirely, flipped it's orientation and re-threaded it. Now the belt pulls down rather than up.
I'll leave this open until Friday once the new belt arrives and I can confirm it's good again
