Printer stops randomly

Running next to another 200+ with no problems it stops and waits for the resume button to be pressed, several times in a print run of 5 hours.
No error message, no clue as to the problem

Hi Norman,

have you tried disabling the material endstop to see if the issue will persist? If it is malfunctioning - the printer will pause the print despite the fact it has not run out of material.

Best regards,
Karolina

I replaced the noisey PCB cooling fan that it had from new so the overheating has stopped and it is now reliable. Dream 3D gave me good service.

Same printer playing up again … similar problem with blank screen and part finished 9 hour print. Switched off as no way of changing it and the Resume allowed me to continue. Has happened 4 times in the one run but the last time there was a screen that said “Blackout detected”. and I pressed Resume. What does that mean?
