Howdy guys and thanks for the support. I have read everything I can find about micro stepping and really dont understand the results I am seeing. I have a Keling 36v power supply and controller and 425ozin motors. I have the controllers set to 3amps. I originally setup my machine with 1/16 stepping and was losing .330 in z while cutting a 3d sample model from Aspire2 (vectric). I have ensured enhanced pulsing is selected, I have the sherline 1/2 pulse mode selected. I changed the stepping to 1/2 and my z was off by .500 within 5 minutes of running. So I went to the other extreme and set it to 1/64. I was able to finish the model (4"x4") and was off by 0.085 when done. I have no more selections for microstepping, even though I dont understand why more microsteps would reduce loss steps, how do I get this dialed in. I have the x and y axis set at 30in/min with acc set to 2. I have the z axis set to 15 in/min with acc set to 4. Assuming these are the only values left to play with, which way do I go?
