I am not really intending to play with the laser input, its only the part involving the 4 wires between the board and power supply and the others that might be added between the board to control the laser shooting by the z axis, if applicable.
thanks for the concern

Hello Khaled,
Did you read the thread I created with simple language?!
So, I'm gonna help you...
Those 4 wires between your PSU (that works by 2 PSU at the same time and feed the board plus the the laser tube) probably are: 2 wires; 24v/Ground to power up the board. And the 2 more wires provide the laser signal from the board to the PSU to fire the laser. Take a look at your board and you'll find out what are the 24v/ground and laser/in controler wires.
Did you get it?
Regards
Raphael

yes i get so I use it as in your case instead of the TH and Gnd, I have them as 5v and Gnd...yes?

Khaled, my friend,
You are saying that your PSU only has 5V input port? It doesn't have TH?
It doens't matter where the old board is conected to your laser PSU, now it has to be conected to TH and GND. Dir pinX( X because I don't know which pin on your 25 pin serial port you gonna use to get the Z dir to fire the laser) goes to TH and ground to GND. Find out where is TH and GND on you PSU and conect like I did.

Raphael, if you look at my ps pictures above you will fin the 4 wires connected to ps from the board are called 24v, gnd, 5v and L, not TH at all

Khaled,
How are you?!
"L" probably means laser.
Can you take a better shot of your moshiboard and show me how those green wires conect to the PSU? I think a draw sketch would be better.
I'm almost sure that to power up the board are being used 24v/Gnd(output from PSU), and to fire the laser are being used L/5v(input to PSU). If I'm right you'll have to conect the dir pinX (X can be any Z dir pin you setup following your board user manual).
Show me a Sketch and I'll see if I can help you.
