Puppy error / Unexpected invalid current
Hi,
I've done a few small prints (5h +/-) on my XL and one large one (> 20h). The prints were just fine.
The printer also reported two errors on startup on separate occasions.
The first was a puppy error. Unfortunately, I didn't note the error number, but it disappeared after flashing the machine to the current 4.7.0 firmware and rebooting.
The second was "Unexpected invalid currrent" https://prusa.io/17303. I switched the machine off and inspected the heatbed for scratches and broken cables as advised. Couldn't find anything that was obviously broken, so I rebooted the printer and it seemed to work.
Should I be worried and contact support, or is this shaky firmware with false negatives due to self-test race conditions on startup?

Of course you should contact Support, this is not normal behavior.
