Thanks for that. However, I did that..I always zero my offsets before creating new one. The Quickcam software created the variable depths of cut it seems so I need to trace why and how! All good fun.

I am maching a rocking horse drawn in ProDesktop. It has just machined successfully but I am concerned about the depth of Z cut that the machine is using. On the Machining Plans I told it to step down by 2mm but it steps down by as much as 8 in some areas. I have just gone through the process again ...
