I have built the first of the Z skates for OverlapStrap.They can be tightened using the 4 M4x40 bolts, and when tightened just right they run very smoothly. I haven’t had a chance to upload any drawings of the parts that make it up yet.
This image gives you an idea of angles at which the bearings are arranged.
Great. You have come up with several good inovations. Keep it up. I'm following you on the reprap aggregation pipe line.Arvin
I have used a similar approach for my z-axis. Key difference is that instead of a rod, I'm running the bearings along another aluminium angle. It also runs smoothly and seems to be quite stiff to resist lateral movement
You are a genius :D, and i got a few clues how to do this myself too… THANK you
