RE: [CAD_CAM_EDM_DRO] is 210 oz/in way overkill for a Sherline

I haven't heard anyone mention the idea of using different sized motors
on the different axis's. When I was running a Sherline a 135 in/oz was
plenty on X and Y, but was straining on Z. A 210 on the Z seems like it
would be a nice solution. After all, there is no reason all 3 motors
have to match.
