Duet wifi print stalls
-
Hi Folks,
It's been some time since I first equipped my detla printer with duet 3d WiFi board.
I have run a number of successful prints however now I'm facing issues that I cannot resolve.Problem:
With longer or prints my printer suddenly stalls.
Previously I run prints overnight fine but now after 1h or 2h it stalls.
By stall I mean printhead stops moving (randomly) but heaters keep heating (OMG!). Web GUI shows printer state as "paused" but nobody paused the print...
When I hit Resume button only one axis moves. Sending G28 also fails as only one motor moves.Restarting via "emergency stop" or power cycle fix the problem.
Today I run 3 times into this issue and couldn't finish prints.
I have a M122 output from two last attempts:

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet Firmware Electronics: Duet WiFi 1.02 or later Firmware Version: 2.01(RTOS) (2018-07-26b2) WiFi Server Version: 1.21 Web Interface Version: 1.22.3 I thought it's an SD card issue and replaced it but again print failed.
I don't know how to find the root cause as currently I'm really nervous of leaving printer alone as when stall occurs heaters keep heating and print could burn after a while...
No additional errors occured.
Thank you for help
-
please update to the latest duet firmware and try again (2.04RC version as 2.03 has a bug with deltas)
-
also. did you follow dc42 suggestion to decrease your microstepping to the recommended x16 with interpolation?
-
@Veti yes
Ok I'll update to recommended firmware version and let You know.
The only thing that bothers me is that printer generally was working fine until yesterday so I wouldn't blame firmware in the first place as it looks very similar to SD card issues (but I replaced it and then same problem was encountered).
How about power supply? Undervoltage event should be visible in m122 command shouldn't it?
Shall I enable some additional debug verbosity level? (And how?)

Ok i upgraded firmware to 2.04RC4 but it didn't solve my problems directly however with new firmware onboard when the "stall" occured in the Console window I got message saying that print was paused due to low voltage.
I replaced my power supply and restart the print.
So far it seems that this problem is gone and it was connected to faulty PS.
