Extruder 0 has no filament sensor

Dave Parry

@dave-parry Do I need to define the end stop with M574?
I have used the following:-
M574 U2 S1 P"e0stop"

alankilian

It looks like your wiring is fine (except for the colors man ) so that's not it.

I do not have an M574 for the extruder stop, so that's probably the problem since it's defining a switch as the endstop type for pin e0_stop.

Also, make sure you have e0_stop in your M591.

Dave Parry

@alankilian No I only just tried the 574 command, as I thought that might be the problem;
I'm using
M591 P3 C"e0_stop" S1

I have noticed that the led flashes Red-Green when no filament in and irregular green when printing. I assume thats correct.

@dave-parry

The only thing I can think of is to use an Ohm meter to check your black wire is complete.

Do you happen to have an oscilloscope or a USB analog capture device so you can look at the signal coming out of the sensor?

You could also use an LED and a resistor. (I'll have to think about how to do that a bit.)

Maybe someone else sees something I'm missing.

You've got a D0 in there right?

Dave Parry

@alankilian Have checked all the wires with a meter, from the back of the duet through to the pins on the connector. I also checked through to the pogo pins for the gnd and 3.3 v but the data doesnt go to them so cant check futher than the connector.

Dave Parry

@alankilian Where does that go?

alankilian

Just for fun, I disconnected my sensor and did a power-on and I get:

m591 d0
Duet3D rotating magnet filament monitor v1 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, no data received

So...... We can forget about wiring.

Something else is wrong.

Can you type this in the GCODE console and report back the results:

m591 D0 P1 C"e0_stop" S1
m591 D0
m591 D0 P3 C"e0_stop" S1
m591 D0

Here's what I get:

m591 D0 P1 C"e0_stop" S1
m591 D0
Simple filament sensor on pin e0stop, enabled, output low when no filament, filament present: yes

m591 D0 P3 C"e0_stop" S1
m591 D0
Duet3D rotating magnet filament monitor v1 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, no data received

Dave Parry

@dave-parry Ah yes I have
M591 D0 ; display filament sensor parameters for extruder drive 0

after the M591 command.

alankilian

@dave-parry

Try the test commands I posted above you.

OK!!! You've got it configured now.

If you wait a minute or so, do you get a report with mag and agc:

Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check every 3.0mm, version 3, mag 129 agc 118, no calibration data

alankilian

filament monitor v1

We may need some extra help from @dc42 to see if there's something different with the v1 filament monitor vs. my v3.

Dave Parry

@alankilian Not got that message yet and it wont home now. I get Error G28
failed to enable end stops.

Dave Parry

@alankilian I only just got this about a month before christmas, so dont understand the V1

Dave Parry

@dave-parry Restarted it and it's now homing

Dave Parry

@dave-parry Have rechecked the commands and I now get this
m591 D0
Duet3D rotating magnet filament monitor v3 on pin e0stop, enabled, sensitivity 28.80mm/rev, allow 60% to 160%, check printing moves every 3.0mm, version 3, mag 133 agc 60, no calibration data

So it is V3

alankilian

@dave-parry

OK!!!

You're all set.

You'll get calibration data after you start a print.

What do you think the problem was?

"C3" vs. "e0_stop"

Dave Parry

@alankilian No sorry Alan, I meant I put the Gcode commands in manually and it reports V3. If I power on/off it goes back to no sensor. It does however display extruder drive 0 data in the status window. If I feed some filament it increments the correct amount.

alankilian

@dave-parry

Post your config.g

You've just got something missing or something extra in there.

You're REALLY close.
