Bigtreetech Smart Filament Sensor Setup

CanDo415

After switching wires from SGV to SVG I thought it will run.
I added "M591 D1 P7 C4 L7 R50:200 E15 S0" to the config.
By testing it with some moving filament with "M591 D1" i didn't receive any data.
Changing "P7" to "P1" in the config gives me switching states of filament present yes/no.

Does somebody has an idea why P7 didn't work as suspected?

Take a look at this thread?

What firmware version are you using?

CanDo415

I read it it over and over again but didn't find it.
Firmware is 2.03

Phaedrux

Can you update your firmware to 2.05? Upload this zip file to the system tab in DWC. Don't extract it first, just upload it.

Can you show a photo of how you have it connected?

C4 would mean you have it connected to the E1stop, is that right?

CanDo415

C4 is correct.

Firmware is updated.

The new output to "M591 D1" is:
"Pulse-type filament monitor on endstop input 4, disabled, sensitivity 7.000mm/pulse, allowed movement 50% to 200%, check every 15.0mm, no calibration data"

CanDo415

I don't know if it is helpfull.

@phaedrux said in Bigtreetech Smart Filament Sensor Setup:

@phaedrux

CanDo415

no ideas left?

Phaedrux

I guess I was hoping the wires would have different colours so I could tell which wire is going to which pin.

Maybe you can guide me?

CanDo415

@phaedrux there is a dot, a thin line and a filled rectangle on it to guide.

Phaedrux

Thanks, that helps. So it looks like it's wired correctly based on that previous thread.

Can you try: M591 D1 P7 C4 L0.5 R90:110 E3 S0

If that still doesn't work I might consider updating to RRF3. RRF2 is starting to get stale. Even 2.05 is over a year old now.

CanDo415

hi @phaedrux

Also setting up my printer with firmware 3.2.2 delivers "Pulse-type filament monitor on pin e1stop, disabled, sensitivity 0.500mm/pulse, allowed movement 90% to 110%, check every 3.0mm, no calibration data"

Phaedrux

Ok, and with S1 to enable it?

And start a print to get it calibrated?

@phaedrux THANK YOU
it works. finetuning is needed, but not the problem.
