Pin 1 is the charge pump (enable). Swarfing is correct, the "test axis" buttons in the config wizard don't work if your BOB needs the charge pump signal, however you can test in the software itself. HINT: you need to click the "power on" button and "toggle e-stop" in the software before you can run gcode. Then you can test each axis in the software using either the jog functions, entering gcode manually into the MDI tab or by importing and running a gcode file.

Longer term, I'd suggest you install DraftSight CAD and dxf2gcode. Then you can quickly create drawings, save them as dxf and then run the dxf2gcode program to create gcode. There are probably better ways to do that, but I'm also a LinuxCNC newby and that is the easiest way I've found so far...
