Great on concrete.
Mine is no problem on concrete floor even with the head RIGHT at the top.
On a timber floor I think it would be no good. Put it on a 3/8" plate if the floor is wooden, with a few welded bumps to keep the feet form skidding.
I reduced my rapids, so my brain could keep up. 100 ipm X, Y and 60 ipm Z. and rapid stops are not a problem. I use 2 separate setup files, one for manual use slowed to human speed, and the other for fast stuff.
Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
