i'm new here, but not new to smoothieboard (i already have 5 printer running this wonderful controller).
I'm here because i'm skilled in mechanical design but not that skilled in software. I've seen on Thingiverse (/thing:454584) a really good open source filament width sensor that is already implemented in Marlin firmware. It will be great to port this also on our smoothie, and i already tried to do but my skill are really too low for this.
I think that this feature becomes a standard in all 3d printers because we can use lower quality filaments (and lower price of course), or diy filaments made from scrap or home extruders, without loose quality or actually increase that!
So, i hope i focus someone of you on a new important feature that i'll like to see in smoothie.
ps. This sensor is even more reliable but i don't know if it work the same as the implemented one (/thing:704897)
