Magnetic sensor reads sensitivy wrong.

@alankilian even if agc is correct it has no affect on my issue sadly.
It seems like the magnet is hitting the pcb so it is not spinning now. So something is wrong. Since agc is correct could it be a defective sensor? It should not be hitting the sensor if agc is within spec right?

@Alucardi said in Magnetic sensor reads sensitivy wrong.:
the magnet is hitting the pcb
Try adding small pieces of paper between the PCB and the case now to get the magnet a little farther away from the sensor.
I think you ALMOST have it working.

@alankilian i there is another issue with sensor. Look how it looks. This can’t be normal.
-
What looks wrong to you?
It looks just like mine.
-
@alankilian top of the axel looks rough but seems to be ok.
-
You said it was grinding against the sensor a little bot. That probably make it look different from mine.
Just add some paper strips here until the magnet turns freely, reassemble it and see if it works.

@alankilian added paper between the housings and that seem to have done the trick.
You happen to know if it is possible to calibrate e-steps with this?

HEY! That's great news!

Hmm.....
What are you thinking?
The sensor measures how many times the wheel goes around.
How would you go from the sensor output of mm/rev to total mm extruded?
Could you measure the diameter of the wheel and use that?I calibrate eSteps using the "Measure 120mm, extrude 100mm, measure the leftovers and see how close to 10mm it is" and it's been fine for me.

@alankilian i do it like that to. but i thought this would be a more precise tool to use. It says "measured sensitivity 25.43mm/rev, min 97% max 103% over 410.6mm" i assume that means over 410.6mm of filament.
