My question is this - both my pc (main board) and cnc machine are 25pin female connections, do I simply buy a 25pin male to male cable? or would I need a different setup as I found a parallel port 6040 on ebay and the cable supplied was a male to female connector?
A picture would help. Is this 25 pin (D25) on the back of the PC as quite often there is a D25 that is a serial port and not parallel. Or is it on the mother board? ie headers
