What i am doing wrong with mach3?? trying to config machine.

[i2i]

Edit: The pins could also be this way round depending on the how the Sheet reads.

X Step =2
X dir = 5
Y Step = 3
Y Dir = 6
Z Step 4
Z dir = 7

That looks right.

the drives look like parker sd2/3, and they have 12v logic so you may need a level shifter to drive them.
