Excellent job so far! Keep them coming!

I also have used a ShopBot. You are way more secure than the old models the Mechmate was based on.

As for your Z axis...
What happens when you power the control box down?

Does it sink?

I'm considering some updates to my old Shopbot, linear bearings, ball screws and a new z axis.

Thanks,

Could you post the parts you used?

I reached out to Jerry via his business email because I too was interested in his linear rails. He got them from
Anaheim automation- tbi rails, 20mm.
The machine is apparently still running very well

These ? https://www.anaheimautomation.com/pr...D=543&dsID=569

I'm not sure if they are the TRS or TRH but yes those.

Haha. Thanks Jerry!

That looks good!
I'm working at the complete partlist and the Solidworks construction + EPLAN drawings. For me a lot to do before starting to build the frame..
