Emergency stop without input

MortarArt

Twice now, my Duet Wifi 1.02 printer has E-stopped, without any interaction. The console reports:

Cancelled printing file ****.gcode, print time was Xh XXm
Emergency Stop! Reset the controller to continue.

The second time this occurred a dialog popped up in DWC stating that the firmware still reports that it's halted, asking whether I want to restart again. Restarting again resulted in a printer reporting idle.

Firmware version is 2.02(RTOS) (2018-12-24b1)

I have a PanelDue attached, and no separate E-stop wired up.

Is this likely due to a fault in the panel?

@MortarArt have you consider updating to at least latest v2 firmware wich is 2.05 if you don't want to update to v3 firmware!

@MortarArt most likely the PanelDue cable is picking up interference from a nearby cable connected to a stepper motor. More recent firmware versions have improved protection against this type of interference.

If you still have access to DWC. Upload these zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.

That will get your firmware and DWC up to date.

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.

Backup your existing config files in the sys folder in case you want to switch back to RRF2. It’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.

These documents will come in handy during the conversion.

@dc42 That's interesting that you're able to do a software fix for hardware interference. I'm curious how that works. But I think I'm happy enough with confirmation that this could be the panel.

I'll update the firmware and see how I go.

@Phaedrux Thank you for the detailed instructions!

If you update your firmwares, don't forget to update the panel due firmware as well.
