G150 is the Special G-code to generate multiple paths to Mill Rectangular Pockets  at given center!.

i will make a pythen Gui for G12/G13 G150 Haas like Milling Cycels into th Simple G-code Generator side !

for all ho like this G-code here is a Equal for Axis EMC!

SOME of you folks wanted to have the original G150 as a parallel path so here is G150.1

upload:rectangular_parallel_pocket_subroutine.ngc

upload:rectangular_pocket_parallel_mill_routine.png

1. Rectangular-Circular Python Pocketing Generator

some of you may prefer a Generator also : put this file to your Nc_code folder by right clicking it and save to then open it in axis -> on some OS you may have to chmod to executable first!
