General Mach Discussion / Re: MI2000 CNC machine from 19's year

Not sure if I can explain my thinking but I will give it a try…
1) Your stepper motors should ‘lock’ when your complete system is connected and powered up.
2) You have said:- ‘What I can see are if I disconnect the parallel port from the computer the CNC says one "click" noise and then you cant move any axis by hand, if I connect the parallel port into the computer it make a "click" noise and then I can move all 3 axis by hand.’
3) My opinion is that you need to find which (LPT) wire is disabling the machine and then set your Mach3 configuration so that particular wire is either ‘Active Hi’ or ‘Active Low’ so that your motors ‘lock’ when the machine is connected to your PC and powered up.
Hope this helps.
