It's Mach3 version 3.043 which came wit my 6040 cnc router so it's kind of chinese licensed. It might be limited on functions, i couldn't say if functions are locked because i am a hobbyist and also a beginner in cnc world, but for me it works, especially the functions i need and use basically and i'm happy that my new system is now more stable and reliable than the 6040 one.
