Describe your issue:

I’ve had this SV08 for just over a month, however I have been having intermittent issues with the MCU Overflow error mid print. The problem does not allow me to use fuzzy skin, or exclude object - guaranteed fail.

The problem however is now getting much more common, and it’s probably 50% failure rate now no matter my slicer settings.

I’m printing mainly with 0.6mm nozzle, 0.2mm layer height, 200mm/s, 4,000mm/s^2 / 600mm/s, 20,000mm/s^2 travel.

From the klipper logs I can see the buffer is emptying before failure, but I’m not sure why the problem seems to be getting worse?
