DIR+/- and PUL+/- motor, but single STEP and DIR signals

[Clive S]

Hello,

Sorry for I am a newbie on CNC...


I am trying to connect a motor driver with 4 wires names: DIR+, DIR-, PUL+ and PUL- to a control board that only have 3 wires: Axis_enable, DIR and STEP...

I am missing something, are these not compatible or is it that DIR- and PUL- should be grounded and STEP=PUL+ with DIR=DIR+?

Thanks!

Welcome to the forum Cyrille. Depending on the BOB you have usually you would have STEP=PUL+ with DIR=DIR+ both connected to 5V+ and STEP=PU- and Dir- going to the BOB
