@TommyDee, I have a Cube3 and two cartridges still in OEM wrapping. Our local library has given up on theirs, although it was working great the first months of operation. So well, I bought one. Now that I've gone through the grief of helping them keep theirs working, I've put mine in a corner (closet) collecting dust.

I've tried to follow the threads that provide for upgrading and improving the printer, but I've gotten buried by the substantial differences in the various messages.

It would be great if there was one comprehensive "instructable" for converting the Cube3 without replacing stepper motors or controllers but modifying the nozzle and feed system is reasonable.

What's a good route to take in that respect? Are you willing to give away your secret to fix the bowden tube problem?
