TinkerDJ,
If you've got 3/8 16 allthread,( and that's the common lead for 3/8,) then for turbocnc set (1/16)/200 or 0.0003125 full step and halfstep would be 0.00015625.
If your board follows the schematic then if you have it jumpered (so pin 10 is to earth) that's half step. I'd suggest you use halfstep if possible as fullstep on 5804's can be a bit rough.
You've said your settings are 1000mhz? or do you mean the default 1000Hz setting for max speed? if so that's 1000 steps per second or 9.375 inches per minute, halfstep. You could try increasing that until you loose steps and back off a bit. It could go faster I suspect.
