Duet3 v3.3 6HC Magnetic Filament Sensor = 'sensorError'
-
@surgikill -
If the magnet is too close, it can easily happen. Then you will often have "too litle mowement" and if the scratches are quite deep, then probably "sensor error". I did it too
. If you can solder well, only the sensor can be replaced. It is relatively cheap.I recommend assembling the MFM really carefully. Take your time. Do not be afraid to use sandpaper and, if possible, define the axial clearance of the shaft minimum as possible.
as @alankilian writes, feel free to put under electronics a piece of paper to get the ideal AGC value. smaller, better but too small meant potential contact between the shaft and the sensor.

@petrkroupa Yea the scratches are pretty deep. At this point I'll probably just use a microswitch. The magnet has caused more issues than it has fixed. I should have just done that from the beginning. The laser one didn't work worth a damn, and now the magnet one, which I thought would fix all my issues, doesn't work worth a damn. $100 gone.
Do you have a PN for the sensor? I can solder a new one on.

@surgikill - AS5601. I2C magnet sensor. Find it on some inet shop.
Do not give up. When MFM works, it's the best filament sensor I've found so far. He just wants a little kind of assembly.

@petrkroupa It's not that. I have product to ship and I can't be dealing with a sensor that does not work and ends up causing issues on prints.

@petrkroupa Well I bought some of those magnet sensors on amazon and they came in today. They are AS5600, not AS5601. Are they still usable, or are they too different?
Also, this is the circle on mine.
-
@surgikill I'm not sure but according to the internet it is 5600 for electronic potentimeter. Angle range 18-360. Which is not appropriate. You need a complete turn.
Nicely scratched wheel. If no metal is visible, the sensor may still work. But it's not certain.
-
@petrkroupa it doesn't look like there is metal visible, but it's hard to tell with the brass that is embedded in there. I still get random "tooLittleMovement" notifications, so it's not working right. It will hold 94-107% solidly, then a random "tooLittleMovement" notification shows up.
-
@surgikill - If you have a camera on the printer, record when printing. If an error occurs, look at what the MFM LED showed. It is quite possible that the green indicator flashes 3 times that the sensor has restarted. This can be because the sensor is damaged or you have a large clearance on the shaft.

@apak Can you start a new thread and share some details about your setup, the issue, and what you've tried so far?
