Soo I just finished assembling my fully loaded x-carve a few days ago, and have already run quite a few tests. I am having a big issue, my machine cuts some very uneven shapes, however always the same. Then I first noticed it was then I was cutting out a heart, it simply looked terrible, I tried adjusting the pots on g-shield, however without any luck. I did a few tests with a pencil and I have been trying to draw all kind of shapes, and all shapes gets a little uneven. Worst are the circles, I have attached a picture.
Does anyone know have I am to fix this problem, it really frustrates me. I have double-checked all the wheels and tightened all the rails... Even did a few live tests drawing circles while adjusting the pots, with no visible change. However if I look at the x-axis' stepper motor while running then it comes to the "uneveness" it kind of makes a bumb or something.
Any help would be much appreciated. Thanks!
