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’.

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

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?

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)

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

Thanks for posting the pictures, they help a lot.

We have established (via PM) that the e-stop is not latched in the stop position and that the stepper motors lock when the machine is switched on. This means that you will only have to find the step and direction pins to get the axes moving – there should be no drive enable signals to worry about.

The first thing you will need to check is the parallel port on your PC.
As a general rule older equipment (such as your CNC machine) uses the 5 Volt TTL standard and more modern equipment (perhaps your PC) can use the 3.3 Volt TTL standard.
From a fresh start of your PC and with no software running use a multi-meter to check each of the PC parallel port pins with relation to pins 18 to 25 which are GND (with luck you will find one that it TTL(high). If it measures approx. 5 Volts then everything is OK but if it measures approx 3.3 Volts then, in my opinion, you will need to use another PC or fit a new parallel port card to your PC which has 5 Volt outputs.

The CNC machine’s step and direction pins could be any combination of pins 1 to 9, 14,16,17.
Probably the most common usage is X axis 2,3 – Y axis 4,5 – Z axis 6,7 but your machine could be any combination and it is a laborious process to find the correct combination however, with patience it is doable.

Thanks :)

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

If you see on picture number 4, you see that the parrel port goes to another card and that is the picture number 5

The machine have LPT i think, but it is  IDE cable for the machine

btw, what is seriela interface?

Maby you can know what this is? if you dont,  try to draw all this and see then? Here is a video of the cards!

Here is the pictures
The orange input connection is for the step motors

I think this is the card for all 3 motors



And this is where the parrel port is connected to



the small card with the red thing is where the parrel port goes to first i think




And here is where the parrel port is connected! the card, this picture is behind



The card with the red cap
