Any hobbyist grade solutions for adding automatic tool changes to onefinity?

Hey Tom,

@TMToronto

With the new X50 rails, I do not think adding a new (better/more flexible?) Z axis system that pushes the centre out 1-2cm more would be as much of a concern.

I agree.

I also consider buying and using a second 80mm mount. Right now the linear bearings being used are 70mm long, and the 80mm mount is 51mm high. If four ne

I was about to order one, too. But then I thought, I’ll wait first how it looks the way it is.

Right now the linear bearings being used are 70mm long, and the 80mm mount is 51mm high. If four new linear bearings are purchased that are 50mm long, then the overall double mount would be 102mm. The minimum amount of Z travel we would then loose would be 102mm - 70mm or ~ 30mm.

It is good to have these measurements. I’m still waiting for my machine so I can not measure this.

I did not think of shorter bearings, that’s a good idea. 30 mm loss of Z travel is really not much, but we would only loose so little if the two 80 mm mounts would touch each other. I imagined the two bearings were further apart so that the leverage is really well distributed. See other Z Sliders. The further apart they were, the more weight you could put on them. Also if I would want to use the retrofit ATC Adapter for my existing spindle instead of a new ATC spindle (I’m not decided yet), I would say that such an ATC Adapter requires a second attachment, but a bit higher. In both cases, you would really need longer Z rails, otherwise you lose a lot of Z travel length.

But in any case, the shorter bearing would be something I’d like to try out (in the future when I’m ready). Do you have a source for it?
