Hey Thanks for all that input.
Guess I’ll need to start from scratch for that matter.
The Sisyphus big and small table used the pinion mechanism but is belt driven.
- Need to ditch the scara arm mechanism because it’s quite a hassle to assemble it, making multiple is really tough.
- Will start on a pinion design with belt like Sisyphus.
- Is there any way to make sure that the belt does not loose tension overtime? I have tried all sorts of tensioners and 3d printer parts for that but eventually it becomes loose.
