@demonio669 I bought the new 30mm bondtech's motor and the hardened gears, yesterday I installed it and I made 2 prints without failing.

It was bondtech lgx fault! not filament monitor!

Bondtech lgx does not have enough power to pull the filament.

@dc42 I'm interested

Can you add accelerometer to the list and that the connectors where compatible with e3d Revo micro?

@Edkirk +1 I also want this board!!

@T3P3Tony no, i'm waiting to try it on 3.4.7 or 3.5.0 (not RC)

Please Excuse my english

Some tips:

• Check filament flow rate is lower than the nozzle can handle . I have e3e Revo Micro and this page has useful:

• Try to put the spool over bearings to minimize the pull the spool makes to the sensor

• Check the sensor wheel is clean and if don´t cleanit by removing the plastic stuck in it

• Check the extruder is not loosing steps

• Check the extruder e-steps is correctly calibrated (if you send 100mm to extrude (G1 E100, you measure exactly 100mm )

@gringo glad to help you

@gringo do you send M955 P0 C"spi.cs1+spi.cs0" command ?

Re: Configuring Type 4 = sensor with microswitch

Today I connect a microswitch to filament monitor and configured to use it ( type 4)

I think there is a bug in the M591 D0 output it shows:

Duet3D rotating magnet filament monitor v4 with switch on pin io6.in, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 4, filament present, mag 132 agc 38, measured sensitivity 25.75mm/rev, min 97% max 103% ove

It finishes in "ove" instead in "over xxxx.xx mm"

@Phaedrux no, I took the value from here:

I don't know how to messure, I'll search internet to find out
