BTT Smart filament sensor setup

Terradive

I have a duet 2 wifi. RRF 3.4. I'm still pretty new to this. I think I have a BTT smart filament sensor wired correctly, but I'm hoping to rule out any problems in config file. I've been using this topic, but the link to the original sensor is expired soooo....link to the product's pdf: https://github.com/bigtreetech/smart-filament-detection-module/blob/master/manual/smart filament sensor module manual201125.pdf

And config file.

@Terradive what problem are you actually seeing?

Terradive

@Terradive Jay I keep getting a low filament movement error and it pauses. Then I resume it goes and pauses etc. When I use an M591 d1 command during printing it says no feedback given.

Terradive

@jay_s_uk I have also installed a .9 stepper motor on my extruder. I tried doubling the l amounts to compensate but that did not owrk.

jay_s_uk

@Terradive can you try increasing the E value to 22 from 15? IIRC that's these recommended value as the sensor only reads every 7.5mm

Terradive

@jay_s_uk I did. It printed longer but still gave the too little movement.

jay_s_uk

@Terradive what results are you getting back from it when it fails? M591 D0 (or D1) should tell you

Terradive

@jay_s_uk No data received. I set the r value down to R1:200. It still stopped in another test. I'm trying to rule out any gcode problems assigning drives. I think I have the wiring correct.

Terradive

@jay_s_uk It's printing using tool 1.

jay_s_uk

@Terradive best to check your wiring then

Terradive

This is my wiring. Do you see any problems? I've tried printing from both drives neither works. They're wired identically.

@Phaedrux This user has emailed me asking for a warranty replacement. Maybe use a X/Y/Z end stop to rule out a board defect on the E0/E1 ports?

Phaedrux

@Terradive Can you check for continuity on that cable with a multimeter? It's acting like it's getting nothing from it.

As elmoret suggests, do you have a simple endstop you could connect and test as a simple filament presence sensor?

Terradive

@Phaedrux I moved the xstop cable over to the e0 slot and tapped the button a couple of times. The light flickered. I'm not real great with multimeters, I unplugged the cable at the sensor. With the printer off, I then put the positive connection to the v wire and the negative connection on the ground. The numbers changed slightly. I then turned on the machine and repeated the test and the numbers changed more.

When you installed the 0.9 stepper did you also modify your E steps per mm?

So it sounds like the E0 endstop is responding correctly.

@Terradive said in BTT Smart filament sensor setup:

I'm not real great with multimeters

To test continuity of the cable going between the endstop port and the sensor you would set your multimeter to continuity mode and then touch a probe to an end of the wire at the same time. The meter will usually beep when there is a connection.

Here's an illustrated example of it. https://www.wikihow.com/Test-Continuity-with-a-Multimeter

Can you show a screenshot of the gcode console after sending M591 D0or M591 D1 depending which tool you're using after it has paused?

I don't think there is anything wrong with the Duet itself.
