I saw this and thought I would post it here for you guys to see. I don't know if it would work for solidoodle but it seems pretty cool

I am intrigued but I'm not sure I understand from his images. I will watch with interest, thanks for the link.
I have seen similar mechanics before... it is neat but directional compound error will get you in the end unless you add components to make it closed loop.
i read it 3 times and i still don't understand how it moves, any explanation?
I think it might rotate around the smooth rod.
Therefore when you rotate the rod, the part travels up and down.
I have heaps of bearings sitting around, maybe I'll print one of these as a test.
looks like the bearings work like a thread on a nut because they are set at an angle/pitch
in the comments says it moves 1.8mm a revolution
im still unsure on how the bearings get a firm grip on the 8mm bar
heres a site that somewhat explains how it works. The issue is that if it slips which it will if it has to make a fast change or the load is to great.

All of you have been so helpful, and now I understand something today that I didn't yesterday! What more could I ask?
