Hi all,
need help badly, I have decided to replace the Bob with a usb 100hz unit. (since my computer with a lpt port went bang)
so I got this onenow I can't get any motor to run.
I have found two different wiring diagrams. A). which has +5v going to the pul/dir +5v.(loop). and the pul - and Dir - (3 wire). this gives a very slow oscillation but no real movement
and B. has Dir + pul+. Gnd looped across the gnd on the driver and ENA+ being feed by the 5v+. nothing but locked up motors
I can see a pulsing led on the Bob (flash in time with the computer)
running mach3
is there any other way of wiring this up that im missing?
anyone using the Bob that can give us a copy of there wiring?
thanks mark
