Maximum Spindle RPM Post Modification for Haas pre-NGC

This post in intended for educational purposes only. Use at your own risk!

This is the Haas - A-axis (pre-NGC) post for Fusion 360 which has been modified with a maximum spindle speed parameter.

When used any toolpath that has been programmed with a spindle speed greater than the maximum set by the parameter will have the spindle RPM's reduced to the maximum set by the parameter. The feed rate for these toolpaths is reduced in the same proportion the spindle RPM's have been reduced.
