Hi, leadshine is a china brand of good quality stepper driver (automationlogic seem to be leadshine model DM856 for example, there is a lot of re-branding within leadshine drives) I like the digital version (DM series, you can tune out some resonance, work well). I don't know much about the

Andy, Marcus, Claude, Gene; Thanks for the feedback and the link. I logged back on to say that I had purchased some of those DM856 controllers, enough for my 4 axis mill build, plus one spare, just in case. I do have a larger lathe that I'm trying to get myself to CNC - an Emco Compact-8, and

John, If I can get the shop straightened up a bit in the next couple of days I will try to show a 00-90 being cut on the Derbyshire(tiny), the Griz 9x20 (middle size), and the Monarch 10EE (just right). Most people are more impressed with the 10EE making the tiny screw than they are with the
