Several time lately with Astrobox 20.4, the print stops unexpectedly after an hour or two. I can click pause and then resume and it starts again and finishes the print. This never happens on the many shorter prints I’ve made, for which the total printing time is much longer than these few long prints, so I don’t think it’s a random communication problem.
That said, I’ve tried a shorter USB cable which hasn’t helped. I’m using a modern RPi 4 with a 3A power supply, which I think is sufficient.
Any other suggestions what I can look at?
