Intermittent pausing mid-print
-
Hello everyone,
I have been using the Duet3d filament monitor for a few weeks now. I started noticing that the printer is pausing mid-print and the pausing is not consistent nor is it lengthy (maybe a second or so, maybe less). Can anyone suggest what might be causing this? I double checked and didn't see anything in gcode that would add pauses (same gcode that i printed months before and didn't have any pausing).
I'm currently on v2.03 of the firmware.
Sensor output from M122 below
M591 D0
Can anyone suggest what might be happening and where do I go from here in troubleshooting this further? Thanks!

I took a video of what's happening while it's pausing.

Do you have a duex expansion board?

Hi Sam, yes I do.

I am having those exact issues at the moment. It seems to be electrical noise that is causing it with the duex board. It was fine for firmware version 2.02 and below but after updating to 2.03 and 2.04 now it is doing it. Apparently upgrading to 2.04 was meant to fix it but it doesn’t.
I would suggest moving your endstops to your main board as David thinks that is the issue. Mine worked ok for a few week and then it started again last night. I managed to sort it after cycling the power a couple of times. I think I may pull the printer apart and shield everything as it maybe a problem that is there to stay. I disconnected my filament out sensor that was the only endstop connected to the duex and it has stopped the Ethernet issues where I was getting lots of dropouts.
Hopefully David can chime in with some more help as it is painful. He did recommend rolling back to 2.02 but I am hanging in there for the magnetic filament monitor which will need 2.04 I believe.
Kind Regards,

FWIW... I may have found the cause of my 'pausing' issue. It appears that it was caused by a short of some kind on the extruder stepper motor, on the duet side(?). I repositioned the cables around the stepper motor connectors on the duet side and so far have not experienced this issue.
I also want to add that in addition to the issue being intermittent, it was present whether the rotating sensor was enabled or disabled (so it was not a problem with the sensor or sensor config).
