I am planing on purchasing a 3 axis kit for my cnc and am wondering if this kit needs additional stepper control drivers to finish it or is it built into the board? I don't think the seller can understand my question. Thank You

Every thing is included in the kit


The power supply, the board which will provide power to the 3 stepper motor

and the breakout board to interface from parallel port to the board.

You don't need anything more than that.

Thanks again Jeff...I was overlooking "optical," should have double checked..too good

[linkintiger]

but they dont tell you that this board is so bad that it might not work at all.

[jeffrey001]

I never had good luck with those kind of board.

Now, I always use one driver per motor.

Sometime, with multiple driver board, when all 3 motor run at the same time,

it look like the board cannot push all the necessary currant.

I don't know about this particular board.
