Heya Hood

Ok I tried running a g code program (roadrunner) and watched from the diagnostic screen as it scrolled thru.
Nothing on leds?
Should I not see something coming on and off?
Also tried plugging parallel connection into micro mill controller and nothing.
Ok I don't actually know machine works but..

Whats EPP ECP how do I switch too?

Thanks Jolyon

Ok you wont see the state change unless you physically change it (by shorting etc).

EPP and ECP are Enhanced Parallel Port and Enhanced Capability Port, sometimes you can change in the device manager, other times you have to set jumpers on the card itself and  other times you can't change it at all.

Sounds like however you may not be having problems with the port at all, if you have a volt meter you can easily check to see if you are getting outputs. If you set the X axis to Step pin 2 and Dir port 3 you can then put a voltmeter between Pin 3 and a Gnd pin and jog one way then the next, you should see the voltage swing between 5V and 0V depending on the direction you jog.

Have you definitely got the X axis enabled and set to pin2 and 3 and also the one that I always miss, set the port to 1 for both Step and Dir?
Next make sure you are counting the port pins correctly, the Mach manual shows a diagram of the port on the back of a computer.

yes x enabled yes x pin 2 and 3 yes ports for step and dir configured as port 1
Don't have mach manual but i'm looking at female connector (ie one without pins)
orientated 30 that 13 pins are on top row and twelve beneath
pin 3 is 3rd from right on top row
pin 25 is bottom left bottom row
is that correct?

Yes that's all correct, not sure what to suggest next other than if its a dual port have a look in device manager and see if there is another address, if there is set it as Port 1 in Mach and see.
 But if the pins are changing state when you short the inputs then it does seem to be working, can you confirm that that is the case?
