Hi Angel,
ok i will try to increase the torus radius, now I have too much play I’ve tryed to print your original design with both a professional 3d printer and my tevo tarantula but the result is near the same I have too much play and another problem I have is that the motor isn’t fixed strong enough and it is able to move a little when it try to rotate resulting in skipping of the shaft.
I’m also trying the ball bearing design of Martin. I’ll make some test when I’ll have some free time and I’ll give you some feedback.A question: do you have a skype account?, It would be great to have a talk so I can also show you my issue in a videocall.
Thank you very much.
Regards.
Andrea Aglietti
