Rotating Magnetic Sensor - Keeps Pausing Printer

@t3p3tony
... and one more time tonight on a different print job:Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 26.50mm/rev, allow 20% to 130%, check every 3.0mm, version 3, mag 130 agc 75, measured sensitivity 26.27mm/rev, min 96% max 135% over 6625.2mm

@wouldstain please send a M591 D0 after the pause.
@charlesmc the sensor does take into account retraction. It looks like the pause was generated because your minimum dropped to 17% (which is below the minimum you have set). The question is why its below the minimum. It could be because there are lots of short movements and retractions in the print, it could be because your extruder is slipping slightly (maybe on very fast moves (i.e. the sensor is doing its job) or something i have not thought of. It would be helpful to have as short a bit of gcode as possible that recreates this drop to 17% or as close to 17% as possible.
I have the same issue, EVERY print I lunch, ALWAYS in the first layer after made the initial perimeters and after 3 lines of the bottom infill the sensor pauses the print because the minum drop to 14%..this happens ALWAYS at the first layer after have printed the perimeters...later on the print the sensor seems to work
This is an example GCODE:Very Fast Test Print__PETG Amazon Basic_0.2000mm.gcode
Let me know

min -9% max 109% over 2162.1mm
can you send me the print file that causes this. also please post a pic of how you have the MFM attached to the extruder
-
@thedragonlord thanks for the example print file

@thedragonlord thanks for the example print file
you're welcome! I hope it could be helpful

@thedragonlord could you also post a pic of how you have this mounted please.

uh now I'm at office so I can't do this, I'll do later now I try to explain: I've mounted the sensor BEFORE the BMG extruders, there's almost no space between the sensor housing "exit" and the BMG "entry" (of course they are attached with a PTF small tube)...any case this evening I'll post a photo if the description isn't enough
EDIT
this is a picture I've just taken with my infrared IPcam...as you can see above the BMG there's the sensor housing, is this enoguh?
-
@thedragonlord yes thanks

@thedragonlord @wouldstain thanks the mounting arrangements look good. I hope be be able to investigate this with the gcode you uploaded here later in the week.

ok, thanks

@t3p3tony this one is interresting:
Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 26.50mm/rev, allow 20% to 130%, check every 3.0mm, version 3, mag 132 agc 76, measured sensitivity 19.53mm/rev, min 100% max 100% over 12.0mm
happening repeatedly on a smaller print.Drywall_Anchor.gcode

If it could help I've discovered that the Magnetic sensor "doesn't like" theese two Ideamaker settings (that's the slicer I use). Unchecking both of them the false errors reduces a lot but, of course, this can't be the solution because in this way you get bad prints....

@thedragonlord I have been working on replicating the very fast error print you sent through
Please can you send through the two macros that are called by your start gcode:
M98 P"Print_gcodes/print_petg_pressure_advance.g" ;pressure advance M98 P"Print_gcodes/print_start_gcode.g" ; start gcode operationsI get not "great" results but not nothing like as wide a variation as you see
measured sensitivity 24.45mm/rev, min 70% max 103% over 219.2mm
measured sensitivity 24.53mm/rev, min 71% max 103% over 140.2mm
measured sensitivity 24.64mm/rev, min 71% max 104% over 100.9mm
measured sensitivity 24.89mm/rev, min 72% max 104% over 61.5mmas an aside, you may have already resolved this but this is an error in your config.g (its not related to this issue):
M350 E16:E16 I0
The second E should not be there

Yes, these settings probably cause a lot of short moves with retraction which may be related to the issue.
