Based on Andy's success having the ball attached to the rod instead of to the effector like I was trying to do, I may take the 1/2 inch Delrin balls that I purchased for my original testing and drill them out to insert my CF rods into and try it his way. I am still convinced that thin parachute shock cord will work for the spring.
My first priority is getting back to having a functional printer, so that means that I will need to use the magnets and parts that I already have printed for now. When breaking the magnets off, the one attached with ABS juice was not as secure as some of the ones held on with CA. I cleaned my ball end mill with brake cleaner to remove any residual oil, cut clean 1/2 inch cups into the effector and carriages, and will use a different brand of CA to attach my 1/2 inch spherical magnets once they are done soaking in acetone to remove the old CA residue. Then, it is back to re-calibration since everything but the rod length will have changed.....
