Looking good Sam, similar to what I did to my Sheldon, but my motor mount is a sliding plate on the front of a much bigger 1/2" apron so I can screw drive the belt tension, and with stepper/servo's, only a 2/1 ratio stepdown. X speed max is just over 60" a minute with a 2NM 3 phase stepper motor. The rest of my apron has the encoder dials to drive it by hand. Seemed the ideal place to put them. Put them near where the cranks used to be. Feels natural. I sealed up the tunnel the x screw is in, top and bottom so swarf can't get to it unless its past center going in. And I put bellows on the z screw on both sides of the nut for its swarf protection. I even drilled two of the nuts 6 holes all the way thru so rapid z movements could let the air get from one bellows to the other w/o sucking in contaminents. > On Thu, Apr 7, 2022 at 8:18 AM Sam Sokolik <samco...@gmail.com> wrote: > > Most likely it needs that movement because it can spin 30 + inches ;) If it can spin 30", what is the max spindle speed? > > sam > > > > On Thu, Apr 7, 2022 at 5:46 AM andy pugh <bodge...@gmail.com> wrote: > >> On Wed, 6 Apr 2022 at 20:22, Sam Sokolik <samco...@gmail.com> wrote: > >> > The cross slide has around 17 inches of travel...
