hello all,
in my 3 axis cnc milling machine, x and y axis runs on rack n pinion arrangement. z on ball screw.
with dsp richauto controller i am controlling the motion profile.
x axis has resolution of 71 pulse per mm and y axis has 35 pulse per mm settings. as y axis is heavily loaded, it is through a gear box.
the problem is when i give command for circular motion, i am getting oval shape instead.
it is only for circular motion and when i use only single motion of axis, the distance traveled matches with the actual settings.
so what probable is the problem and the solution,
i really need to solve this problem earliest.
