Shut down all heaters on fault possible?

  • I had a heater fault which aborted a print. It turned out to be an intermittent connection at the connector for the bed thermister. I never leave home or sleep while printing and I live stream to my phone if I have to leave the vicinity of the printer so I caught it quickly. However I noticed that the hot end was still active and the print stopped at the spot it was in directly on the print. Is there a way to make it where all heaters turn off on a fault from any? Call me overly cautious.

    I wouldn't expect a bed heater fault to abort a print. But you've reminded me that executing pause.g when a heater fault occurs is on the wish list.

  • It just stopped and the hot end was still active. Excursion beyond 10C. Bed heater shaded purple and non responsive. Clear heater 0 fault did nothing either on Panel Due or web interface and I went back to documentation to be sure I entered it correctly. Print showed 100% in web interface and on Panel Due clicking print tab displayed as if it hadn't been started. X, Y, and Z displayed correctly. Home worked and setting the hot end to 0C worked. Bed temp display worked. I did manage to get the bed back on by clicking the inactive in the web interface but it was still shaded purple on Panel Due. Hit the hard reset on Panel Due but it was unresponsive as if it wasn't hooked up to Duet after the reset. I had to shut down the PS to get Panel Due back to functional after reset. Afterwards I raised the bed out and turned it on. Mild pulling on the thermister wires at the connector on the Duet revealed a fluctuation in the temp reading. The connector was seated good. Turned off and reseated the connector and couldn't get it to fault with mild pulling on the wires. Ran out of time, but going to cut the connector off and put new end on. Pause would have been awesome.

  • BTW, using latest stable releases. Not at printer now 1.17e IIRC?

  • I just cut off the connector and crimped a new one on and the readings are solid when pulling on the wires. Wouldn't you know, it was the only one I didn't change when I went from Smoothie to Duet.
