Rotating Magnetic Sensor - Keeps Pausing Printer

@wouldstain Probably better to start a new thread on that, thanks.

I have put new 3.4beta5+1 binaries at https://www.dropbox.com/sh/xeu30go894p9xbs/AAB5U66SH4wbjKIcX0snUbKxa?dl=0. These fix a bug that was giving me consistently poor results from the filament monitor on the drywall-anchor print. This particular bug was either introduced or made worse in version 3.4beta2. The particular instance that triggered it was a very short extruder move, less than one microstep long. This means that it would have occurred more often on machines with low extruder steps/mm.
Use these binaries with caution, because I have done only small test prints with the Duet 2 binary, basic movement tests with the Duet 3 binary, and I have not yet tested the Duet 3 Mini or Maestro binaries.
These binaries also include the race condition fix that may have caused occasional incorrect results from the filament monitor in firmware 3.3 and earlier versions.

I'll give it a try with the same gcode I've posted earlier and I'll let you know... just for info my printer uses two bondtech BMG extruders so I haven't configured a low step/mm for them

Good news so far!
I've reprinted the same gcode and it went all ok!
M591 D0 Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 24.78mm/rev, allow 60% to 130%, check every 3.0mm, version 3, mag 131 agc 65, measured sensitivity 24.54mm/rev, min 95% max 112% over 1356.0mmso far so good!
More tests will follow!
Thank you guys for your effort!
EDIT:
It doesn't work anymore the Telegram bot I use to have all the printer notifications...have you changed something? -

Ok, I wrote here because the issue started this morning after the installation of the last pre beta

I can confirm that the sensor issues has been solved by your FW patch...I've made several small prints and one large prints in dual material using both the sensors and I had no problem at all
Thanks again
-
@thedragonlord thanks for your help in working through this and providing some test prints. Can you confirm your filament monitor settings, PA settings and what filament monitor results you are now getting.
@wouldstain have you had any success with the new builds yet?

M572 D0 S0.75 ; Pressure Advance M572 D1 S0.75 ; Pressure AdvanceI alway get results around 95-98% as minimum

@dc42 Duet2Combined.bin for Duet2 Wifi?
Also, what is the .map file? Is that something I need?Thank you!
-
@wouldstain you can ignore the map file. This is a build of RRF 3.4b5+1, are you running 3.4b5 already? If so then you can just update to this version using the Update system files in DWC->System. If you are not then please update to 3.4b5 first (DWC as well as RRF)
-
@alankilian if you have a chance to try the new version that would also be helpful, thanks.
-
@t3p3tony I'm on 3.2.
Can you send me the upgrade instructions and links to the revisions I should install?
I've got a 30-minute test print that fails so I can test quickly.
-
@alankilian thanks, if you are happy to make the upgrade then please follow the following steps.
First upgrade to 3.3:
- download the Duet2and3Firmware-3.3.zip file from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.3
and use "system" -> "upload system files to upload it. it will prompt you to install the updates say yes. - Assuming that all goes as expected DWC should reload and you should see 3.3 versions reported for DWC and RRF in the General and Machine Specific tabs in DWC.
- To get around a issues with future upgrades (we switched from /sys/ to /firmware for firmware binaries between 3.2 and 3.3) the best thing is to re- upload the Duet2and3Firmware-3.3.zip again at this point. you don't need to re-install the updates. this just ensures stuff is in the right place for future upgrades.
Second upgrade to 3.4b5
- get the Duet2CombinedFirmware.bin and DuetWebControl-SD.zip files from here: https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta5
- Upload the firmware binary first and say yes to install the update. then upload the SWC zip.
- check that the firmware and DWC are now reported as being 3.4b5
Finally upgrade to the 3.5b5+1
- Get the Duet2CombinedFirmware.bin from the dropbox link posted earlier. There is no updated DWC.
- uploaded it as in the previous step, say yes to the update
- the Machine specific tab/M115 should report 3.4.0beta5+1 (2021-10-29)
- download the Duet2and3Firmware-3.3.zip file from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.3

Board: Duet 2 Ethernet (2Ethernet)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.0beta5+1 (2021-10-28)Started a print and almost immediately I got "To much movement"
Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, version 3, mag 133 agc 114, measured sensitivity 16.39mm/rev, min 100% max 100% over 12.0mm
Resumed and checked again:
Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, version 3, mag 132 agc 114, measured sensitivity 25.89mm/rev, min 94% max 102% over 78.4mmPrinting completed.

Second try: Too little movement:
Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, version 3, mag 130 agc 114, measured sensitivity 26.55mm/rev, min 2% max 105% over 118.3mm
Since my AGC is almost at the high limit, I'll do a little sanding to improve it and try again on Monday.
-
@alankilian thanks - it might be the agc, if not then please share the file that causes the too little movement.
-
Here's the test file: CalciumCup.gcode
I'll adjust and try printing a few more times on Monday.
My sensor is just below the extruder and moves around a little bit with the bowden movement.
I should probably move it above the extruder.I'll also try that on Monday after getting the AGC in a better range.
-
Unfortunately, I can't get the AGC under about 115 without the pointy-bits of the brass roller starting to scratch the surface of the sensor chip and not moving all the time.
You mentioned stronger magnets. Are they available?
Otherwise I may try sanding the top surface of the sensor chip a little.
I figure there's enough plastic above the sensor I can get the tiny amount of space I need to get a better AGC value. -
@alankilian yes if you drop me a line (info@duet3d.com) i can look at arranging a replacement assembly.
