Possible test without the board ?

Hi,

I've some encoder laying arround, is it possible to use them with your firmware ?

The filament monitor uses a relatively simple protocol to send the angle to the Duet every 50ms or so. I have not written up the documentation for the protocol yet, once I do then you could use a MCU to interface any encoder to the Duet using this protocol.
