Multi-spool mode Freeze failure
After 2-4 hours, the screen goes dark and freezes. The touch panel does not respond.
The buffer is empty, the filament winds around, the buffer switch remains on, and feed is stopped.
There has been no failure so far, and the set values and environment have not changed.
The difference from before is that the machine gets hot.
It will be fixed by restarting, but it will always recur.
Please tell me the cause and countermeasures.
Is this a good question?
