… as well as EMT conduit tables.
And the 525 roller piece is too much fun to play with, so I made this clamp:
to be uploaded soon is a bearing bracket that will hold a 608 bearing in the middle of the roller piece. The hole in the middle clears a NEMA17 stepper and 608 bearing. Woohoo!
This should let me use foot-long 3/4 EMTs as legs and big flat MDF as base, the machine be its own table, and then install a leadscrew (or 5/16 allthread wtf) at each corner. Then come attachments to support a full size drop table supported from 4 corners meaning I should be able to use something more hefty. Of course the 4 steppers driving them would be run in series, maybe with some multiplexing tricks to allow driving only one of them at a time to facilitate leveling.
Next is a version to mount a stepper perpendicular to the conduit.
mmm. Smells like fun.
