Repetitave profile increasing z axis

[cadman@teluspla]

Does anyone know if there is an shorter way to write this type of a program?
it keeps repeating to a depth of 2.55" at 0.05" per

[drewmeister]

do it in a sub routine. make your first z move a incremental move and do not have the cutter move up and the end of the sub.

[Geof]

I see you have the Z-0.05 at the top of the first set of profile coordinates then Z-0.10 at the top of the next: Do you mean you keep on with Z-0.15, Z-0.2, etc until you get to the full depth?

Put your profile coords in a subroutine and then increment the Z-0.05 before you call the subroutine.

EDIT: Drewmeister must type faster than me. He wasn't there when I started.

Thanks for the input guys.
It all helps

By using the M97 with the L command will let it loop so having your entire path with in the P1000 program and using G91 for the Z Depth it will continue to repeatedly do the steps you want.

Hopefully this will help.

you can also use a While do loop:

This is my macro to trepan maybe this will help
