Hi,

I use Mach3 at my CNC mill with the Benezan break out board (http://www.benezan-electronics.de/manuals/Breakout7-Installation.pdf) and I am very happy with this.
But in future I will use a 4 axis, so it isn´t a problem to conect at this board.
My problem is, my 4 axis has a hydraulic brake and I need a digital output from Mach3 to lose this hydraulik brake to turn the 4 axis.

How can I solve this problem?

Regards Stefan

Hi,
you need a second port. This will require that you fit a second parallel port card to your PC. Not all parallel ort cards work,
I would recommend buying one from PMDX, they have selected and tested a working card. You will also need another
breakout board, you could get another of the one you already have or you could get one from PMDX.
