Yes, looks like you are going to have a constant battle with the laptop I am afraid.

I got the pulse frequency back at about 25k and change the configuration as you said, gave it try and nothing again.

Then I checked the volts at the end of the printer cable attached to the Laptop and between pins #3,5,7,9 and ground I get 0V. I found that strange and went and changed the printer cable to another one 10 feet long now and with all pins connected on it, I think they call this cable straight through.

So if I get 5V on the Laptop printer output and after I connect the cable I get 0V at the end of the cable what this means.

I did check myself the printer cable for continuity between each pin and its ok. I also jog the axis with the keyboard arrow keys when I was testing for volts

It means you are maybe checking the wrong pins?

Time to open a Johnnie Walker bottle and celebrate LOL, it works !!!

I bought today a used DELL desktop, installed XP, connect it to the machine and now all is fine. Motors sound very smooth and quite

Now I have to install the 2 home switches on the Y axis (X & Z switches are already installed), do some testing to make sure nothing is loose, and square the gandry.

After I finish the above I will have to do the power supply unit (didn’t forget)

Thanks so much Hood,
Nicolas

Glad to hear it, laptops can sometimes work but they are normally more hassle than is worth it.
