No matter what i do my home built machine do like the image you can see on this link
http://www.geocities.com/kyllop/cnc.html
When I want to draw a square the x axis drive fine, the y axis drive fine BUT
when it comes to the last drive on the y axis it stop before the end.
I use mach3
I have try to change the y steppermotor but it's still the same.
i have a gear 3/1 on the x and dirrect drive on y (belt).
and have config mach3 to 600 step on x and 200 on y.
Any one know what's wrong ?
