parralell port voltage.

ok read i should have port as ecp in bios...
and something weired...
i start my laptop (with meter still connected) i get a steady 4.77 volts. then i start up mach3 and still the same. as soon as i shut mach3 down i get 25mv.. i went bach into mach and nothing 25mv.

its now in active low.ports n pins inputs...! pin is 0 still enabled. still no number changes, when pg up etc is pressed.. is this the root of my problem...

[crossleymarko]

might i add i have nothing plugged in.. ie breakout board etc.. software dosnt do anything when cursers are pressed.. maybe thats part of the problem.. no cooordinate change at all.

That's a problem. Try going on to the MDI tab and in the white box type:

G0 X10

That should make it move to X=10 and you should see the numbers count up on the DRO. Send a screenshot if not...

Have you tried running the Mach driver test?

Silly question:
When LinuxCNC starts up it will disallow all control of the machine until the user clicks the magic EStop button - effectively saying they are in control of the machine and the environment. If I remember Mach works in much the same way, a big red stop button perhaps? Have you clicked it?
