Machine is older, it is actually Mikron Haas VCE 500, but the control is very similar/equal to newer Haas mills.

We have problem with this machine that it doesnt finish contour (toolpath) very precise, for example if you make a circle it will leave a small amount of material around start/end point of mill toolpath (circle).

So we deal with this in CAM software, to extend this toolpath for example by 2mm... or make 2 circles instead of one.

But this problem occurs only on this older Haas machine, we have 2 newer and they dont have this problem.

Is there a parameter or setting on the machine which could overlap this contour for some amount so this problem wouldnt occur?

Thanks in advance.
