After 19 hours of printing: Printing paused:heater fault
-
If you got that heating fault message after you reconnected DWC to the Duet after the Duet had already reported a heating fault, then that message is probably a duplicate of an earlier one.
If you restarted the Duet after that heating fault, then I suspect you have both temperature setting and tool selection commands in config.g. I see that you have G10 P0 S200 R180 in config.g. Do you have a T0 command in config.g as well? If so, do you really mean to heat up the extruder as soon as the printer is turned on?
-
yes, T0 is there.
and i keep printer off when not printing, and i found it convenient to heat up head immediately.
by the way, is there similar command to heat up bed?
i still got the same error after ~30 sec after power on....
"Error: Heating fault on heater 1, temperature excursion exceeded 15.0°C"so what is your verdict over my machine?
-
I never expected anyone to put a heating command in config.g so I haven't tested it or thought through the potential complications.
-
i removed G10 from config.g now printer starts without error.
after print starts .... some time later temperature very slowly goes down.
could it be some power issues? i have ordered new heaters, but afraid that would not help .
-
Yes it could be power issues. Check the VIN voltage display in Due Web Control. Also check that the screws in the terminal blocks that the heaters are connected to and the screws in the VIN terminal block are still tight.
-
what kind of AWG will be suitable for 1m cable and 50W heater?
-
Is the heater 12V or 24V?
-
now it is 12v, after upgrade will be 24
-
A 12V 50W heater draws about 4.2A and a 24V 50W heater draws 2.1A. There are tables online giving maximum recommended current for different wire gauges.
-
well, my cable is 0.75 sq.mm. that is more than enough for 4 amps and 1 m... will test other cable, but do not think it will help.
