Is anyone able to look at a log and determine what the issue is? It has happened a few times now and I haven't been able to pinpoint a source. Printer isnt overheating, utilization is always low, etc. Thanks!

SV08 running Sovol Klipper, not mainline.

Could be any old issue with SD cards, some power management thing on the RPi interfering, or just drift between host and MCU, or MCU dropping an ack packet

#

These issues are mostly intractable and people recommend all kinds of things from swapping cables to SD cards to USB ports. On one machine I ran into this during homing, switching to the USB3 capable (blue) ports worked but everyone tells me it shouldn’t matter

#

So best of success finding the magic wiggle to make this work again

I appreciate the ideas. Sovol says it could be a less than optimal connection anywhere from the board to the head so I guess I'll prod it this weekend.
