How do you handle coding a clear point while indexing the pallet on a horizontal machine? I suppose this would apply to a vertical with an indexer also. Say I have the clear plane set to 1.0" which is my usuall setting. When indexing, I may need 8 to 10 inches for clearance. Do I modify the element's clear plane, hard code a clearance value in the .tmp file, create a clear point and just hit it before I change workplanes? Is there something in the .smf file to handle this? I have been just fixing the code in the text editor...I prefer edit free code.

thanks,

Dale,
You can modify your template. I don't know what type of controller you have. Some have a Z home code (GE2000 uses G52 Z).
Here are some examples of what I use for Z clearance on pallet rotations.

You may be able to make your own from some of the examples given here.
Hope this helps
