Magnet Filament Monitor V4 - Calibration Issue

T3P3Tony

@Diamondback ahh yes I see I have not tested the monitors as much with 3.5b1 as I have with 3.4.x are you seeing the same behaviour with both firmwares?

dc42

@Diamondback use the default 3mm unless you get a very large measured sensitivity range, in which case you could use 6mm. As you have the filament monitor a long way from the extruder drive, you are likely to need an even larger range than that.

When running a print, the measured sensitivity should be displayed after about 10mm of filament should be extruded. The length over which calibration has been done should gradually increase and the measured sensitivity range will widen at first and then settle down.

If you pause the print, calibration will restart from the beginning when you resume.

Diamondback

@T3P3Tony I can't run 3.4.5 on the board where the sensors are connected atm since it has a memory leak that was only fixed by @dc42 in a custom 3.5b1+ build for me.

All filament sensors are connected to a Mini 5 in Expansion mode, same board as the extruder motors.

Diamondback

@dc42 Ok, that's the behavior I expected from the documentation, but unfortunately it's not what I see.
After it first displays some form of calibration data, it just stops there and won't calibrate any further. The reported values then stay constant for the entire duration of the print.

If I use the reported values in my M591 call, the sensor appears to "work", as in, it does spawn filament error events when the runout switch triggers etc. However, the calibration distance of just a few mm of course leads to incredibly inaccurate results...

@Diamondback thanks. It may be that there is a bug in the support for filament monitors on main boards used as expansion boards. I will add this to my investigations list.

Diamondback

@dc42 Thank you

Diamondback

@dc42 Some further info, yesterday my filament didn't detach from the empty spool correctly and got caught during a testprint. The active filament monitor did not catch this, it did not generate any filament error at all even after a few minutes of continuing to print.

Its config:

M591 D2 P4 C"100.io2.in" S1 L23.2 R70:150 E5

I guess something is indeed not working?
(The switch part of the monitor works fine btw)

Phaedrux

Did you send M591 to see what it reported after the fail?

Diamondback

@Phaedrux Nope, unfortunately not, but I guess I can easily replicate this. I'll do that when I find some free time

Any news on this?

@dc42 ?

dc42

@Diamondback please can you update your firmware to 3.5beta4 on both boards and check whether the issue still occurs. There have been some fixes in this area.

Diamondback

@dc42 Updated everything to 3.5b4 and it seems like I can still not get anything out of my sensors other than the presence switch signal.

Configuration:

;Filament sensors
M591 D0 P4 C"100.io0.in" S1
M591 D1 P4 C"100.io1.in" S1
M591 D2 P4 C"100.io2.in" S1
M591 D3 P4 C"100.io3.in" S1

M591 D3 after a print using that extruder:

Duet3D rotating magnet filament monitor v4 with switch on pin 100.io3.in, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, version 4, filament present, mag 132 agc 34, no calibration data

(the other 3 also don't show any calibration data, but I guess that's expected since they weren't actually used during the print)

Previously it was sometimes showing some data, but now it's just constantly "no calibration data".

Diamondback

@dc42 anything more I can test or help you with to debug this? I'd really like to get my 4 sensors working beyond the switch signal

dc42

@Diamondback thanks for the reminder. I'll try to reproduce this next week before we freeze 3.5.0 rc1.

patterson6

@Diamondback When you say V4 are you referring about the v3 product on the website that's revision 3.0? The software calls v4 in gcode which is really v3.0 but the fourth revision because of 1.7, 1.7a, 1.7b, then 3.0?

Or is a new filament monitor v4 on the way?

patterson6

This post is deleted!

Diamondback

@patterson6 It's the newest rev of the monitor with the new rod magnets. So based on this link here, it would be 3.0. The V4 is just what the status report returns

@Diamondback please provide your complete config.g file.
