Check this out, someone made a delta without roller bearings, but used magnets all around.
Per the comments, he's using paper napkins as a bearing surface between the magnetic carriage and each of the vertical arms.
Just like using magnetic arms for the effector, I like the idea of "zero-slop" carriages, but I wonder if the "napkin bearings" will wear down in a way that will affect calibration accuracy over time.

Re: Check this out: bearing-free delta
So it's sliding on napkins instead of using rollers? But the magnets are holding the carriage to the rail?
Not so sure that's a step forward.....At first I thought it was a contactless levitating system but it's not.
Also, I'm getting tired of seeing pencil thin arms on delta bots, it kills any rigidity that would have been there otherwise.
