Topic: Table coupler/stepper motor spindle

The stepper motor has a round spindle, so on my assembled unit the table and tilt on the axis of the two screws that hold the table coupler onto the stepper motor spindle.  Does anyone have a good solution for stabilizing this?

Re: Table coupler/stepper motor spindle

I had a wobble problem, but for me it was attributed to the flatness of the printed table.  Specifically, the mating pieces were not totally flat.  I tried to file it and it made it a little better, but eventually I stuck a small piece of paper between the coupler and the table to wedge that side up.  Worked fine.

Oh and I must be using the modified two screw coupler.  It is a really tight fit on my shaft.
