I have the eggbot all together, and all the parts are talking to each other and working as they should.
I am having one problem. The pen arm is slipping. The pen arm is affixed to the pen stepper motor securely via the set screw. However, the wooden part itself slips around that coupling. The wood piece is not firmly affixed to the metal coupling that has the set screw. As the eggbot is drawing, motion of the pen stepper motor is not always translated to the pen because of the slippage between the metal coupling and the wood part. I hope this makes sense. Shouldn't the wood piece be more firmly affixed to that metal coupling? Mine is lose and leads to distorted pictures. Is there a reason that is not a tight/solid connection? Thanks for any advice.
