Hi, you wrote that you wanted to experiment with ESP 32. Is anything working?

What controller board uses this chip ?

[github.com]
The E4 board is a minimal 3D printer control board based on the ESP32 microcontroller from ESPRESSIF, with built-in Wi-Fi and Bluetooth. The controller speed is up to 240MHz, 16M flash.

Hello,

I was wondering if anyone was able to get the filament sensor working on SKR 1.4T. as per RRF; it should be enabled by M591, however when I try to create the sensor in config.g then issue M591 D0 to show the status of the filament sensor in Drive0 or E0; it says that E0 has no filament sensor.
Then I tried running the setup M591 which I have in config.g from the console & this is what I get: M591: unsuitable pin
this is what I have in config.g :
M591 P7 C"e0stop" S1 L100 E3 D0 A1
Although in RepRapFirmware/src/LPC/Boards/BIQU_SKR.h the "e0stop" is defined to be correctly pin 1.26, not sure why it says unusable.

Is there another way to actually define the pin & use it as filament sensor?

Regards,
Molafa.

What filament sensor are you trying to add?

Well, I'm just making my own, using an encoder. it should be the pulse generating one.

in that case, it has to be a pin that starts with 0 or 2. 1.26 won't work as it can't driver interrupts

Okay, how do you suggest I define a pin? as far as I understand the M591 accepts only a pin name for the C parameter.
Can I let's say define "e0det" in board.txt to be e0det= then call in in config.g?
or I could just use the "servo" which is P2_0?

Just use the servo.
You can use either the name or pi number to refer to it as both are supported

servo didn't work, for some reason it's undefined so I tried "probe"
M591 D0
Pulse-type filament monitor on pin probe, enabled, sensitivity 1.500mm/pulse, allowed movement 60% to 160%, check every 3.0mm, no data received
M591 P7 C"probe" S1 L1.5 E3 D0

It only receives data during a print

servo says unknown pin
M591 P7 C"servo" S1 L100 E3 D0
Error: M591: Unknown pin name 'servo'

Its servo0 I think

yes! that worked, servo0 although it didn't say in the BIQU_SKR.h file.

Thanks a million! I guess I can start playing with it.

Its listed on the wiki.
