I have read quite a few posts but am still stumped, I am setting up a rotary axis on my router table but do not have the steps quite right I believe. I have a g203 with 10 microsteps and a harmonic drive rotary with 50-1 reduction. The numbers I came up with is 222.222 and .0036 The first one makes it turn fairly smooth however sometimes when I am jogging it goes the wrong direction, the second number .0036 just makes it growl. Also when the axis indicator rotates once the chuck rotates about 5 times.
