Greetings;
Actually, thinking of the springs out of old 1 wide 15+ foot tape
measures.
Has anyone done this, and taken a pix of how you anchored the ends of the
spring so that there was enough pivot available so that it didn't force the
spring out of shape with potential dirt leaks as it

But yeah, that could work, assuming your screw is longer than your
travel to allow for compression.
Dyson hose has rather an impressive extension ratio..
Indeed. But when I'm at the faceplate I have ~3mm of travel before hitting
the ballscrew bearings - ~550mm of travel from there - I'd

Same here. If I was doing the conversion again the ballscrew would be
shifted 6 towards the headstock end. The part past the tailstock

Hi all,
This is really a response to the LinuxCNC for DIY 3D Printing thread
without hijacking that thread.
After seeing the success of a few other people in getting lcnc running on an
Arm / Beaglebone, I thought I would take a shot at doing the same on the
Olinuxino, with the intent of driving
