newbie with MFM

apak

red led flashes 7 times, it´s a v1 magnet, so how can I fix this issue?

apak

@apak sanded top part and now it´s flashing red/green, will try now

M591 D0
Duet3D rotating magnet filament monitor v3 on pin 121.io1.in, enabled, sensitivity 24.80mm/rev, allow 70% to 130%, check every 10.0mm, version 3, mag 125 agc 128, no calibration data

NEED more sanding I presume

infiniteloop

Does the axis of the hobbed assembly rotate when you push filament through the sensor? If you are not sure, have a look at this thread.

alankilian

@apak It won't get "real" data until you print something.

I'm not sure if hitting the "Extrude" button on DWC will be enough or if you actually have to start a print and wait a little bit.

apak

@alankilian it works fine, I adjust the value, but once pause and resume, the values where doubled and kept on pausing

alankilian

@apak Post the results of M591 D0 before and during the pause.

Also, your AGC value of 128 is too high.

THIS page says what to do about it:

Values for 'agc' of 50 to 105 are considered normal.

If the value is higher, up to 128, the distance between the magnet and the sensor is 
likely to be too large (target is 0.25mm). 

Check that the screws holding the PCB down are not loose (caution: they are 
screwed into the plastic, so don't over-tighten them). If they are already tight, you 
could remove the 2 long screws to separate the two plastic parts and very slightly 
sand down the bottom surface of the top one (the one with the PCB attached) to 
move the sensor closer to the magnet.

getting ERROR 7 every now and then, so I am not able to use MFM

right now it´s disable so I can monitor what happens as it keeps logging data even disabled
