It is not supported like it is used in Makerbots. We only need a pin toggling between high/low when filament moves. Not knowing this device I can not say if such a pin is available there, but it might be.
That sounds even simpler. So you are saying that we could just a simple rotary encoder, something like https://www.sparkfun.com/products/9117 ? There are also more expensive ones that put out 100+ pulses per rotation.
Yes, taht would work for the signals. But question is if friction is enough to safely rotate it and if lifetime is long enough. Others use a hall sensor or light sensor to switch such a signal without mechanical parts.
if there anyway to invert state of pin? I want to install optical endstop as filament detector, but there is no way to invert signal, and when filament goes through sensor it written that it is filament out
