I just bought a Prolight 3000 lathe turning center from a closing school. Came with everything, ATC, ISA card, control box and everything else. I would like to upgrade it tho because the softwaer is kinda limited and computer is old because of isa card. I looked up a little and doing a Mach3 conversion is apparently the way to go. I am very new at this, only have worked with new CNC never modified any. What would be the parts I need? I know I would need a control board but is that it? What brand is the best for this application and somewhat easy?? Thanks!
