You now have two threads going about the same thing, just so you know. Here is my reply to your other post:
"Couple of things,
There is an advantage IMHO with using a profile cut on a pocket. Unless I am becoming really senile there is no spiral ramp option available to finish up the vertical walls.
If the OP is using Mach3 then I would suggest he head on over to Ger21's website and pop for a copy of his most excellent Screenset 2010, he has it for a few other controls too but I am too lazy to go look. Just google up Screenset 2010. What it does is allow for 2 tool touch off plates. One is placed on the workpiece as per normal. The other is located off the work in some known position. When running a job it works as follows:
When the button is pressed the tool advances to the touch off plate on the work and sets a height. Then it goes to where the fixed plate is set up and touches off again. The program then runs the first tool and stops to ask for a tool change. Change the tool. The program then goes to the fixed plate and touches off on it. It does the math required of the difference in tool height and then proceeds to cut with that tool, wash, rinse, repeat. Works really well.
The last time I looked that screen set was $20. It is way, WAY better than the standard Mach screen with other really nice features."
