Hi, Elnino
What you stated is mostly true, For latest ver of LazyCam D-load Mach3R2.00.060 or latest Ver above under Downloads, "Mach releases".
Optimize is working in D-load ver, LC has been split into Std., Pro ver, Pro requires a License, Downloads, "Plugins", for Pocketing, Lathe,
Offsets, ........
Hope this Helps, Chip
