Thank you for your quick reply

I have a minitech mill and they supply the wiring and switches ,a red light
in the switch goes on when touch them with a metal piece ,i think i have
home switches ,the probe and the Z axis switch are working ,every thing was
pre wired and all what i had to do ,is plug it in the controler ,i have two
lights on right now ,X and Y on my home lights on my screen ,the switches
will light up red when i put a piece of metal in front of them but the
travel will not stop
I hope that i make any sense

Would there any one out there ,that could tell me if there any setting beside motor tuning ,that could make a distortion in my milling ,i mill wax ,round become oval and square become rectangle,
On a flat or rotary it is the same ,motor tuning is fine i made a block 10mm and that came out fine ,but as soon as i load a toolpath in it goes wacky.HELP

Sounds like backlash. Can you post a picture of the cut and code. There are several other things that come to mind, but that is the first. Are you sure your steps per are right? Beside each axis DRO you have a scaleing DRO. What do they say?

Brett

what is a dro? i feel stupid
