One of my primary recomendations to newbies is to leave room for large stuff. It usualy does not cost more to leave room for a 1 inch screw when you start out with a 1/2 one. ditto motors. Although I have been doing steppers, I recomend that a NEMA34 space be provided if one is planning on a NEMA23. I am laying out the rails for the unit and will make a simple 18 x 36 becasue I have the parts. Well, actually, It will be a router table when it is all said and done, but that will prove out the speeds and feeds for the plasma. The two are being designed together, but I am more interested in the plasma being done correctly. Dave > > turbulatordude wrote: > > > > >3/4 continuous ? > > > >I have a couple old printer motors.
