@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

@wouldstain @TheDragonLord please also provide your config.g files, to help us reproduce this.

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.

Here are the g files and thanks for the M350!

@thedragonlord thanks, sorry to be a pain but can I also have your heightmap.csv file.
basically looking for anything at impacts the print process.

You don't need to apolgize, you are helping me so it's all ok!
Here's the file:

have you discovered something? The sensor are almost completely unuseful because they keep om pausing even without the two settings...
EDIT:
I was thinking about a thing....could it be that this issue depends from the pressure advance? I'm using it with 0.4 value... -
@thedragonlord I managed to get some testing done this week and have passed the results on to @dc42. I have some more tests to do though. I made a cut down version of your print file, with as little movement as possible to see some of the effect and got 64% to 106% which for movement with no major retractions I find odd. So in summary its not forgotten, but not pinned down yet.
