MCU 'mcu' shutdown: Timer too close - Manta M8P, BTT CB1
Over time, the RAM and CPU usage start to approach and rest at high values. The printer will then error out at the beginning or end of a print. Restarting the host restores CPU and RAM usage to normal values (CPU 5% and RAM 41% while idle). It's not a critical failure, but it would be great to know why system resources are being consumed.
