the controller went out this year. i upgraded it to the controller and motors i was gonna use for my new cnc mill, which im happy with, they are a lot stronger then my old set up, i got it all dialed in so x and y cuts perfectly and precisely better then my old ones ever did, and adjusting the jibs became a lot simpler.
the problem comes when im cutting circles, but only at the top and the bottom, and i can figure out why, i researched the issue myself and have tryed a bunch of things but without luck.
this never happened with the old motors and controller, and i find it odd its only happing at the top and bottom. attaching a picture,
marked the top with the axis directions, and the lines represent where the problems are
if anyone has any ideas i appreciate the help and will try everything even if i already tryed it just so we can rule it out.
