Triangle sensor ordered thanks!

I ended up sending

M591 D0 P3 C"io2.in" L24.93 R30:200 S1 A0

However, I'm still periodically getting too little movement errors. Looks like I'm dipping down below 30%. In the below instance, I caught the system dipping down to 48%.

Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 24.93mm/rev, allow 30% to 200%, check printing moves every 3.0mm, version 3, mag 132 agc 87, measured sensitivity 24.98mm/rev, min 48% max 103% over 816.4mm

My whole objective with the filament monitor is to just detect the end of the spool, so that the system can pause, I can load up more filament, and keep on going.

But it has too many false positives to be useful.

Ack...I screwed up the command that I posted above. I just sent a new command down and it correctly updated the range to 30% to 200%.

M591 D0 P3 c"io2.in" L28.4 R30:200

Just sent M591 D0 L30:200

Just got back...so that didn't update it

	M591 D0
Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 30.00mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 3, mag 132 agc 87, measured sensitivity 24.93mm/rev, min 97% max 103% over 2113.6mm

I'm on layer 249 of a 900 layer print. The print ran for hours, but got a too little movement error overnight and then that error has been increasing throughout the day. I just hit unpause each time to get the print going again.

I had not used my 3D printer in a long time prior to a test print just before this larger print. I upgraded the firmware (Duet 3 mini 5) to 3.4.6 and I turned the filament sensor back on using the following command. I did not have issues with the test print and therefore thought that I was good to go with larger print.

M591 D0 P3 C"io2.in" S2

When I run M591 D0 in the console right now, I get:

Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 3, mag 131 agc 87, measured sensitivity 24.93mm/rev, min 97% max 103% over 534.4mm

Can I send another M591 D0 P3 C"io2.in" S2 L20:200 command through the console to update the filament monitor setting while the print is running? Or is that going to derail things?

Thanks for your help!

I had a successful 13 hour print yesterday. I kicked off a new 9 hour print and the printer kept pausing due to "too little movement on extruder".

This seems to be in line with alankilian's comment above that he had to disable his because he couldn't stop false positives.

Note that there was a pause generated by the filament sensor just before the 6:31AM M591 D0 call.

Any suggestions on how to correct this?

I'd like the magnetic filament sensor to just say...I've stopped rotating completely...must be out of filament so put the system into pause.

Is the sensor not taking into account retraction and rewards movement of the filament?

Ugghh. Yesterday I did two five hour prints with no problem.

This morning, I kicked off a 13 hour print and I just found it 12 hours later where it had printed the first layer and then paused the print for "too little movement on the extruder".

M591 D0 output is as follows

Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 25.74mm/rev, allow 70% to 130%, check every 3.0mm, version 3, mag 132 agc 91, measured sensitivity 26.25mm/rev, min 45% max 106% over 244.6mm

I just opened up the allowable range to 20% to 150% to try to give it a wider tolerance.

That solved it...much better results now....94% to 103%. AGC is now 96.

Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 26.92mm/rev, allow 1% to 200%, check every 3.0mm, version 3, mag 132 agc 96, measured sensitivity 25.21mm/rev, min 94% max 103% over 1721.6mm

After thinking about this more, I think I need to initially set the low and high limit very wide. Then get the measured sensitivity over a print, set the sensitivity to that value and then update the limits to say 50% and 150%.

I just implemented the rotating magnetic filament sensor. My print keeps pausing with a message that "too little movement" was detected on the sensor.

Any thoughts on this?

Here is output from M591 D0.

Duet3D rotating magnet filament monitor v3 on pin io2.in, enabled, sensitivity 28.40mm/rev, allow 70% to 130%, check every 3.0mm, version 3, mag 132 agc 128, measured sensitivity 27.38mm/rev, min 1% max 107% over 78.7mm

Here is what I have in the Config.g file.

Thanks

@fcwilt That's a good suggestion - will implement!

thank you! will do

Sorry - I was confused as well and I think I'm getting the temperature fault because I need to re-tune the bed - apparently it didn't save correctly when I tuned it yesterday.

Should I keep the stuff that circled in red in my Start G-code that is part of my Cura settings for the Ender 5 or should I remove that because it looks like some of those commands will override things that are in the Duet config.g and may not be correct.

Hi - I just converted my Ender 5 from a Bigtree SKR 1.2 running Marlin over to a Duet 3 Mini 5+.

My Cura set up for the Marlin had a bunch of stuff in the G-code header (or start G-Code) which was placed into the top of the G-code after slicing.

I pulled most of that stuff out so that my header just has the following.

However, I'm getting a temperature fault right off the bat when I try to print.

So I'm confused about what should go into the G-code header in Cura (Preferences -> Printer -> Machine config -> Start G-Code)

Looking at the Marlin header, it had a bunch of temperature commands in there. However, shouldn't the temperature commands NOT be in the header and shouldn't they be automatically generated by the slicer since temps may change based on filament?

Current start G-Code in Cura:

G28 ;Home
G29 ;Automatic bed leveling

G92 E0 ;Reset Extruder
G1 Z2.0 F3000 ;Move Z Axis up
G1 X10.1 Y20 Z0.28 F5000.0 ;Move to start position
