Circle is it problem

[bunalmis]

Do you live any problem if you want to draw circle at the
High clock rate for the gecko and big screw (1 inch/rev)

(Gecho driver and DC servo motor)

Well, I don't have a 1" per turn screw but I have 6 turns per inch screw and have no problems with circles.

With a 1 tpi screw you would need to use some sort of reduction anyways so it won't be a problem.
