This something that has bugged me for a while and although I think it will help I’m after feedback and thoughts on this idea.
As some have read and tried Marty’s new upgrade part replacing the springy coupler with a printed one. Since then a few of have gone to full aluminium coupler with the same result as the printed but with a better or more positive mechanical grip on the shaft. I personally had the printed couplers slip.
Now although this works reasonably well I think as higher speed printing I am getting vibrations transmitted into the print.
So to go full circle again I am thinking of re using those springy couplers but in the way they are supposed to be used.
Here is my first attempt of a solution.
So my thoughts are the bearing takes the load of the X carriage and the springy coupler drives the Z axis and my hope some of the vibration and acceleration and deceleration in Z at high speed print is partially absorbed.
I would just run the leadscrew through the bearing and into the coupler to eliminate another chance of issue but at the moment I am just using a printed adapter. I am going to make a aluminum one as well to test, so people could upgrade without buying new leadscrews.
Any thoughts, ideas, anything I have missed?
