Hi Piccyman,
Those Velocity and Acceleration settings are fine also although I think you may run into problems with the axes mass if fitting a Porter-Cable style of router spindle.
In my view, the object of the exercise is not to have the fastest machine on the planet but rather the most accurate and reliable.
You may want to look again at your ‘steps per unit’ as according to my calculations…
20 tooth pulley, 3mm pitch belt, 200 steps per rev stepper, 1/16 micro-stepping equates to 53.3333… steps per mm.
36 tooth pulley, 2mm pitch belt, 200 steps per rev stepper, 1/16 micro-stepping equates to 44.4444… steps per mm.
This, of course, assumes that your belt is accurate (has not stretched etc.).
Tweakie.
