MCU shutdown: 'Timer too close' at the end of VAOC Calibrate Z-Offsets
I went in an mcu shutdown timer too close during the z-offsets calibration process in the VAOC. This is repeatable.
The probeing procedures completed for both toolheads, but at the very end when the offset between the toolheads is calculating it fails and the printer run in a mcu shutdown, quickly.
It looks like the pi is too busy, but i think specially at this point the calculating of the offset is not a very complex (a simple subtraction?).
The printer is in stock configuration except a usb webcam and two BTT sfs v2 filament sensors. It is a VC4 500 Idex machine.
Has anyone an idea whats the root cause of this behavior and how could I fix this issue?
Thank you for your help.

Timer too close is a very generic klipper error. Basicaly, klipper itself does not know what is going on.
Usualy it is caused by some kind of overload of the Rpi.
but how could this be? the raspi hardware is allways the same. The only "changing" thing is the SD card. I did a quick speed test and the result was 37,4 MB/s writing speed and 44,2 MB/s reading speed. I think this should be enough for Rat OS. Am I right?
