Thinking now that im better off running with leadscrews and changing them out with ballscrews after i figure out final design and also for space issues. So far most ballscrews have a flange that boarder on the too big for the space. Im in the process of getting a quote on ballscrews of about 12mm diameter with flanged nut and a lead of 2mm. That way i should be looking at about 0.002mm(2mm Lead / (200 Steps x 1/4 Stepping Controller)) for my resolution. Im sure itll end up more like 0.01mm but that would suit me fine, Worst comes to worse, ill end up using timing pulleys and belts with reduction.
