@Steve I used the initial layer width adj in cura to deal with elephants foot. The results were pleasing and gave that edge a slightly rounded look and feel. -0.125 worked well. However the top part of the gears where not extended into the moving path but they were quite sharp. I went over them all with 600 emery. It would be nice if there was a setting to reduce the top layer as well. That would be ideal. I suspect that the frame may have been printed not 100% perfect. I can print a 30mm cal cube in the center of the bed dead on perfect, but whos to say whats happening at the outter edges. Its a belt driven unit. No linear rails.
There is nothing like the feeling of getting an old clock running. I have had folks drag there old, tired, beaten brass units to me from all over. Into the cleaner they go, install a few bushings, maybe a click spring or suspension spring, oil em' up and start em up. Its a great feeling once it up and running and you get the beat spot on. Thats my idea of excitement. I got that with this project. I guess im an odd duck. :)
At some point when i get a chance, I will share my tested and proven method of a printable zero friction pendulum hanger. It really is slick. First did it in wood. But can easily be printed with great results.
Cheers.
