problem doing circles

[maxelsson]

Hi
I have some issues with my TRIAC. It should mill this cylinder following the blue line(10 steps Z-axis cut increment 1.5mm) but suddenly after done that in 2 steps(z-axis) it starts to short cut and follows the red line. I cant seem to find anything wrong in the NC code I'm using EdgeCam. Can it be something wrong with the stepper motors or some thing else ?

What software is driving the machine & what control/eprom?

[maxelsson]

Fanuc 0M (Denford Fanuc milling 2.73 with the tutor panel). Where can I find the eprom ?

[angel-tech]

what position physically is the slot, in the x or y axis, or between

[maxelsson]

It is between the X and Y axis.

I thought it was going to be a VRMilling issue but not too sure regarding the Dos software.
