Re: home-brewed CNC saw

Are you thinking of a circular saw on a fixed axis so the saw moves
across the work and the work on a long table so it feed to length ?

seems like 2 axis is simple and all you need is to control the feed
of the saw into the part.

I have a chop saw I am doing something similar with. But I am
setting the feed as a chop and moving the part for lenght.
