I would like to know how to post a small square in mdi or from my keyboard to pocket or profile to check the accuracy of my machine. Im making a small bone piano keyboard when posting the black key part the cuts are not square instead this is what i get the g code was checked by bob cad my software  but couldn't solve the problem
thanks

It looks like you need to increase the acceleration of your motors.  The machine is trying to blend into the next cut.  You can increase your motor's acceleration and see if that helps, or you can turn CV off and turn Exact Stop on, that should take care of the issue whether the accel on the motors is slow or not. G64 turns on CV G61 turns on Exact Stop.
I would turn on Exact Stop (G61) only when doing finishing contours; Keep G64 on when roughing.

Thanks I increased the acceleration of the x and y axis my test cut came out ok much better than before but I’m afraid as to where I should push it I also couldn’t cut the cv light off should I just push the acceleration until it looks correct how do I turn off the cv light
