I found this showing the basic wiring for the board.

Does this look right?

A bit hard to read (blurry) but looks OK.  I think you should leave pin 14 disconnected and don't bother enabling it, it's an output.

That did not work.  I believe I am not doing my pins right for input and output.  To get the motor to move, how do I do inputs?  Here is what I am working on now.  Just the A Axis motor.  If I can get it moving, I think I can do XY and Z.  I am using the Hot Keys { and } for A jog.

What do you mean by "how do I do inputs"?  Inputs to drives or the BoB?  As I mentioned early in the thread if Mach3 is expecting to have an estop signal and the appropriate input is not connected then it will just think there's an estop asserted.  Equally for the limits.  Usually these switches are connected to ground and NC so the input is at a zero, so if a wire falls off it "fails safe".  Check the input pin setup in config/ports&pins.  Also look on the diagnostics tab to see the status of the signals.  Mach3 manual should help you.

John, do I put input wired on the BOB other than the dir+ and Step+ from the drivers to 5VDC and negatives of step and dir  the outputs from the drivers to P2 thru P9 for XYZA?  I think I am confused in Mach3 on the config/input signals, output signals and motor outputs.  I put Port 1 on everything for Port but the Pins confuse me as to which to se for everything.  Using a 10 post connection block to go from 5VDC Power supply to 5VDC+ on the BOB and connecting all the Step+ and Dir+ from the Drivers , is that OK?  Also 10 post terminal block from GND of 5VDC supply to P2 thru P9 and also to go to Dir- and Step- of the Drivers, is that OK?  Also the 5VDC Gnd from power supply goes to GNDs on the BOB.  How do do earth GND and where does that go?

Thank you

Ray

Ray, when I set mine up I just followed the Mach3 manual.  Do you have a copy?  If not get hold of one.

Sounds like I need to find the manual.  Thanks John.  Have a pleasant and safe Labor Day weekend.
