Hey there a couple of questions:



  • 1: parallel ports seems a bit out of date, although I've already got "all" the electronics for a CNC mill (3 or 4 axis) - can I buy something so that I can connect to PC with USB or do I need to buy all new electronics? (I've got a Leadshine Mx3660 + another cheapo breakout board)




  • 2: I've bought a lot of CNC building stuff, but back when I got it I didn't actually know which way to go so I've got regular open loop Nema 23 + 34 steppers. - is there any encoders that can be attached to the motors so that I can convert them to closed loop steppers or do I need all new closed loop steppers? ( I ofcause also need somekind of encoder input that can connect to Mach3)




  • 3: I'm guessing closed loop steppers are the easiest/ cheapest way of minimizing the loss of steps/ improve precission - am I right or is there better ways - let me hear your thoughts on this



I'm a student so I'm looking for a satisfying solution on a budget!
(I'm pretty good at the hardware/ machining part, but when it comes to electronics/ software I need some guidance )
