An 1/8 step is a nice comprimise. Going to 1/16 may not do much for you.  So it would be
40 steps / degree x 8 microsteps = 320 steps / degree
Then fool with velocity and accel some to see what works.

I went 1/4 160 etc. I will try higher resolution. Accel and velocity are a little high for a Sherline. Thanks again going in to change jumpers. My next controller will have a hinged top and a dzus fastener!

Never mind I set the A axis to 1/8th step and 320 steps per unit, 2400 velocity and 200 on the accel. I also changed my setting in gen config regarding a axis, unchecked it to make it linear. Why ? I dont see a change in anything? What does that refer to? Angular or linear, though I thought I understood the words just not the context apparently. Any tips there?

There are a number of configuration settings that affect the A axis. In general config angular is measured in degrees and not affected by a whether you are working in inch / mm units and if inchecked it will be measured in linear units just like the other axis. Do a search , type in , ROTARY TABLE AS LINEAR , and you will find a number of posting s worth reading. There are a whole bunch of things associated with a rotary table. I have just used mine as an indexer
but you can program moves in ipm instead of degress , etc.
