MMU2S Beeping During Print but No Issues
Hello,
I’ve had my Prusa MK3S with MMU2S for 3+ years, always trouble-free. Today, during a 2-hour single-material print, it started beeping and showing an MMU2S MCU error, but the print kept running fine.
Resetting the MMU2S stopped the beeps, but it happened again later. Anyone know why this happens if everything’s still printing OK?
Thanks you
