Just set up electronics but no x axis motion

Are you sure Gary? On another thread there was considerable debate about the lack of source current output from the buffers on the ZP5a and the conclusion was it was better to use the BOB to sink current through the optoisolators, therefore PUL+ & DIR+ to 5v and the - to their respective outputs on the BOB and set Mach3 to 'active low'. Which is the way the OP has it wired apparently, assuming the red wire is to +5v. What's hard to see from these pics is the drive to motor wiring; to check the pairing of the 8 wires down to 4.

@skydeal do you have Mach3 set for active low and pulse length to 5? And can you list the motor wiring.

Quite sure.
The N is a gnd, so connect all of the negative sides to this.
the buffers output a 5V step, direction and enable signal, so the PUL+ goes to the S, the Dir+ to the D and the ENA+ to E.
Also don't use the USB to power the board, it is very finicky.

Wasn't my conclusion and I told him this wouldn't be the problem. These Bob's are basic yes but they do work and with what's probably the most used drive to come out of china It would be bad state of affairs if they didn't.! . . . . .Sites would be full complaints and I've not seen many and 99% time it's not what they thought it's some other issue like what Gary mentions being powerd by USB etc.
