I just got a used Liberty cnc router and the parrell cable was bad and now I can not get the pins configured.. I made a cable probing and testing all that was in the control box....I matched all of them up but do not get anything.. Got the ohhm meter and test lights... I just need a little advice on what to do... Please help.... I know just a little of electronics... It has 3 driver boards it has vexta ph265-01 steeper motors x, y and z.... can not get mach 3 to make any kind of movement
Thanks
