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

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!

*This is for Generating simple Pocket Style Toolpathes with Different depth/step-over *Version 1 does only support Zero Path but you can simply edit the final path to G41 *upload:pocket_V1.py *Screenshot : *upload:pocket_v1.png * Written by Sammel Lothar Germany
