So i should take the multimeter and turn on my pc and take the measure voltage on the pc's parallel port connectiion?

Yes.  ;)

I cheked the pins voltage on the pc and it says 4.74v. But if i take the pararell port on the machine and take pin 11 on 12 the spindle motor begin but if i do the esact same thing in mach then nothing moves so i think that i did something wrong when i installed mach

Hi guys! i have still problems! cant get it to work! What i can see are if i disconnect the pararel port from the computer the CNC says one "click" noise and then you cant move any axis by hand, if i connect the pararel port into the computer it make a "click" noise and then i can move all 3 axis by hand. any help guys? I can also see that the computers stearing port is ECP-Writeport  (LPT1) is that correct? or the other port that are called comunication port (COM1)

Sounds like you may have an ‘Enable’ signal after all.

Assuming that the pin assignments on your LPT cable are ‘standard printer port’ then with the machine connected to your PC and Mach3 running change the ‘active state’ (hi / low), one at a time (and click Apply / OK after every change), for each output (1-9,14,16,17) to determine which pin and what state (hi / low) causes your motors to ‘lock’.

In the port settings it says

"Never use interupted" Should that stay on?


and the "Enable search for older plug and play devices" should that stay on?

Sorry Norsk, I did not explain it well - my mistake.  :-[

I was referring to changing the active states within Mach3 (Config / Ports & Pins).

Okay so i gone take one of the steper motor and try from from pin 1-9? or

Not sure if I can explain my thinking but I will give it a try…

1)   Your stepper motors should ‘lock’ when your complete system is connected and powered up.

2)   You have said:-  ‘What I can see are if I disconnect the parallel port from the computer the CNC says one "click" noise and then you cant move any axis by hand, if I connect the parallel port into the computer it make a "click" noise and then I can move all 3 axis by hand.’

3)   My opinion is that you need to find which (LPT) wire is disabling the machine and then set your Mach3 configuration so that particular wire is either ‘Active Hi’ or ‘Active Low’ so that your motors ‘lock’ when the machine is connected to your PC and powered up.

Hope this helps.
