first move not clearing material

[kell]

It is Mach 3 and it dose say safe z not set but not sure how to set it

Unfortunately I don't use Mach3 as yet so you'll need to hang around until someone else wakes up.
I normally set up my safe Z clearance height in the cad/cam software before it gets to my controller.
What are you using to create the G code?

[kell]

I'm using solidcam

I don't use solidcam either so I'm not being much help to you. Somewhere in the material or milling operation setup in solidcam there will be a box for you to input a safe z distance. It might be labelled as clearance distance or something like that. You would normally set that distance so that the cutting tool would be able to clear the workpiece and any jigs or fixtures above the material.

This link has some info: https://alliance.seas.upenn.edu/~med...structions.pdf
Step 3 on the pdf shows a pocket milling operation and has a box for clearance level. I think this is where you put your safe distance value.
