Magnetic Filaments Sensor with toolboard - No Data

LeonMF

I have a magnetic filament sensor which, TBH, I really haven't been using because even though it's mounted an inch above my Hemera and usually reports 90s% to 100s%, it would always fail out on prints with small movements.

I've upgraded my printer to 3.4, fixed my steps/mm on the extruder, and am hopeful that it will work reliably now.

Recent print result from directly connected to Duet:

Duet3D rotating magnet filament monitor v3 on pin (io2.in,i2c0.clk), enabled, sensitivity 26.14mm/rev, allow 5% to 250%, check printing moves every 3.0mm, version 3, mag 128 agc 93, measured sensitivity 26.22mm/rev, min 97% max 104% over 1106.5mm

I just installed a toolboard and have everything working except that the sensor returns "No Data Received". I get blinking green red when not moving and blinking green when moving but no data.

Toolboard filament monitor config line. Note the wide monitoring range because I don't trust a tight range... if I could get this working.

I've quadruple checked my wiring for connections. The pins appear to be secure and well connected and I would presume the red/green flashing wouldn't happen if communication wasn't occurring??

I'd love to get my umbilical between the printer and print head down to just power and CAN but this is blocking me from making that transition. Am I doing something dumb?

That yellow wire looks a bit damaged. Is that the case, or just a trick of the light?

LeonMF

@phaedrux I'm 99.9% certain the wire is OK. I used silicone wires for this and they insulation is made of butter. The internal wire isn't exposed, though.

Would I be wrong in assuming that the sensor would not blink red/green if it isn't communicating through that yellow wire?

Did you have any better luck?
Can you send M122 and M122 B121 and copy paste the results here?
Were you able to test the wire continuity?

LeonMF

@phaedrux I finally had a chance to get back to this and my problem was that the signal and voltage wires were shorted. Those tool board connectors are too darned small!

Thanks for the help!

LeonMF

@phaedrux I take that back. I'm still getting no data received.

(Deleted M122 results)

False alarm. My ground wire pin wasn't seated in the Molex connector on the sensor side and, apparently, worked long enough for me to prepare for a print.
