Re: New arm design for Simpson style printer.

I am in over engineer mode to make sure there is no chance of failure. Optimization will come later when I have time.

I know how to do stress analysis but I am clueless about how to start a wear analysis. Theoretically, all the contact is rolling contact so I would suspect a FEA model would predict surface smoothing but not plastic removal.

Bottomline, I am using the sledgehammer approach right now.
