On some disturbed level, I’m considering a mouse ball.
Take the platform, supporting it from above and below all the way around, but just on the power edge of your build size. Then in the center of that enclosure, add a ball on the bottom. Have two weeks, your x and y axis, turning the ball. I think that would make for some super shitty accuracy and energy transfer.
Right, one bolt under the build platform, one bolt moving the rotary tool.
I should look at the mouse ball for a robot though.
Peter's stuff.
