Driver wiring to my computer for mach3 to control

[irving2008]

So you should have 4 x CN2 connector (rectangular mulitpin)

The diagram you need to look at is 'Position Control Mode' on page 20

Step signal is on 32(+) 33(-) (PULSE)
Dir signal is on 34(+) 35 (-) (SIGN)
Sheild is on 36

These are opto isolated and can be conected to a parallel port directly or via a buffered BOB. I would recommend an active low configuration. In which case pins 32 and 34 need to be wired to a source of +5v from your BOB. 33 is Step, 35 is Direction

There are other connections on the CN2 plug that might be useful to feed back to MACH3.. Servo ready, servo alarm, etc. On all of these the - signal should be connected to the GND line on the parallel port and the + side pulled up to the +5v via a 2.2k resistor.

Hope that helps, shout if you need more help
