Weirdest thing... It's back up now.

WiFi module has been up the whole time (it was responding to pings(ICMP))
Telnet to ports 23 and 80 were getting nothing

I did not connect directly to USB with my workstation and try to print.
I did put a file in the gcode directory on the SD card by hand and was able to print.

I did set up and connect an OctoPi as a possible work around and it did seem to be communicating but I had not had a chance to print with it.

I've been beating my head against my desk for the last 8 hours trying to get this sorted
and I walk away from my desk for few minutes and its back up.

I do not like issues that seem to resolve themselves in this way for obvious reasons.

It may have something to do with burning some sage and swinging a dead chicken around but.... That's dinner so it would have happened regardless.

Just for posterity:

Woke up to DWC not working at all this morning.
Getting blank page. Tried obvious stuff like rebooting.

Was running 3.4b7 all the way around.

Using Duet2Wifi w/ Duex

Built new SD card w/ clean config:

DWC 3.4.1
RRF 3.4.1

Issue persists across clean config and upgrade.
telnet to port 80 produces no output from DWC.

Able to print from SD card via paneldue.

Any help troubleshooting would be greatly appreciated.

@droftarts Will give it a try! Thank you!

Does anyone have any insight as to what driver stall errors could mean? I get a fair number of driver 1 stall errors (normally a few per print job) and occasionally driver 0 stall errors.

This happens on any print job with any settings.

Also, the "download as .csv" and "download as txt" functions on the console info do not seem to be working.

@phaedrux done. thank you!

@phaedrux
Finally got around to reprinting case. Used PLA this time instead of PETG.
It's alot cleaner on the outside but really no difference on the inside.
I ran a needle file through the feed path just to be certain there's no blobs or burrs

Initial reading (before printing first time). As you can see, AGC has gone up quite a bit.

Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 3, mag 133 agc 111, no calibration data

1st test / calibration print on 20mm calibration cube:

35% ona "too little movement error":

Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 3, mag 132 agc 109, measured sensitivity 25.84mm/rev, min 35% max 106% over 983.4mm

adjusted M591 while paused to:
M591 P3 C"e0_stop" S1 D0 L25.84 R35:130

Print completed without further error.

2nd test completed without error.

3rd test printed 2 x 20mm calibration cubes simultaneously

Stopped at 88% with the following:

M591 d0
Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 25.84mm/rev, allow 35% to 130%, check printing moves every 3.0mm, version 3, mag 132 agc 109, measured sensitivity 26.05mm/rev, min 0% max 109% over 2811.8mm

So... Even with the new case, it's still randomly stopping.

I'm thinking there's a problem with the MFM.

@infiniteloop No doubt! I'm still pretty new at this and I generally assume it's something I'm doing. Given what you're saying about post processing and my questionable print quality, I would not be surprised if there are tolerance issues with my casing.

@infiniteloop I have the MFM sitting directly atop the extruder and the PTFE tube comes in close to vertical so I'm not concerned about the angle of the filament path.

I am considering picking up a piece of copper tube from McMaster and replacing the bit of PTFE tubing connecting the MFM to the extruder but I really dont think that's where the problem is.

I'm inclined to print a new casing and giving that a try as I noticed that the ring on the MFM sensor from the magnet rubbing was a partial circle which would indicate to me that there's a slight tilt to the magnet.

I think an injection molded case would remove any uncertainty around it but I'm not certain that would resolve this issue.

@phaedrux I havent but I can although the casing is clean on the inside. I had some first layer issues IIRC and it still has some dry bedweld on it (got distracted and forgot to rinse).

@phaedrux

Photos as requested.
Please let me know if there's something else you'd like a pic of.

@phaedrux As soon as the current job is complete I'll get some photos.
Assuming you want to see it mounted as well as on the bench and disassembled.

@alankilian I can tell you for certain the extruder is not clogging.
I've actually set up a macro to disable the MFM when printing PLA:

   M591 d0 s0

This allows me to run entire PLA jobs without interruption but also without the protection of run-out detection. I was able to finish off the tail ends of two spools yesterday thanks to having the MFM enabled but there were several false-stops during the process.

@alankilian gapped with some paper as suggested.
Same issue:
m591 d0
Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 25.63mm/rev, allow 1% to 200%, check printing moves every 3.0mm, version 3, mag 131 agc 74, measured sensitivity 33.09mm/rev, min 1% max 132% over 61.4mm

@alankilian Thank you!
I'll definitely give that a try later!

@alankilian I had not looked at distance between sensor and magnet as a possibility. Any suggestions on what the distance should be?

@infiniteloop I actually marked the idler so I can see it moving. Also.. when I put it together I did some filing to makes sure stuff was moving freely. I can pull filament through it manually and it feels like it moves smoothly.

@Phaedrux @dc42 @T3P3Tony

I've been dealing with a long-term recurring issue with my MFM where I keep getting the following error:

Filament error on extruder 0: tooLittleMovement

There seems to be no rhyme or reason behind it. I've run off several of the same print, sometimes I get no errors, sometimes I get multiple errors such as below. At this point, I am able to resume from the Status page button with no other action.

The only common thread with this issue is that it seems to happen with greater frequency when printing PLA. I am able to print a complete PLA job with the MFM disabled but that leaves me with no filament run-out protection.

I dont want to toss the MFM out but I'm getting pretty frustrated by this problem.

@phaedrux

I think this version has improved PID tuning and made a big difference in another problem I've been experiencing.

Can you link most current beta? Or better yet... Is there a permalink to the repository? I keep getting dropbox links which go stale plus i cant just modify the URL to navigate up some sort of directory tree.

Thank you!

@Phaedrux

I've been seeing an issue with the hot end not responding to temperature changes via DWC or M104 after an extended idle period. (overnight).

It starts responding again after power cycling or issuing m999 command.
