    Default Machine won't run

    My CNC router has 3 NEMA 34 Stepper Motors, 3 MondoStep 7.8 Bi-Polar Stepper Motor Drivers shown at https://www.probotix.com/CNC-CONTROL...r-Motor-Driver, PBX-RF RF Isolated CNC Breakout Board shown at https://www.probotix.com/CNC-CONTROL...Breakout-Board, USB SmoothStepper shown at https://warp9td.com/index.php/products/#details, Mach 3 software, and Windows 7. The machine worked fine before my woodshop teachers moved it from old building to new building. Now, nothing happens when I try to jog the motors. I found out that some wires came off the stepper drivers during the move. The stepper drivers and/or the breakout board may be damaged. I tried to check and fix the wires but I couldn't do it.I want to replace the breakout board and USB Smoothstepper with an USB breakout board like the one shown at https://openbuildspartstore.com/cnc-...-mk3-4-4-axis/ Please help me fix the machine.

    It sounds like your machine should work, you just need to re-attach the wires that came loose. I doubt there's more damage than that, if it wasn't under power when they were disturbed. The thing to do is figure out which wires are detached, and where they should go. If you could post some pictures showing exactly what's come loose from where, and perhaps a schematic of your system, it's likely someone here could help you get it back to working condition. If you want to start replacing things anyway, I'd suggest getting it to work as-is first, if possible.
