Hi Michael

Thanks for the reply. I do not know what the model is, but one can use either the RS232 or parallel port. It has 4 ports at the back to which stepper motors are connected. There are also 2 cables connected.....one serial cable and the other a parallel cable.

I can open the serial port and I know that there is a link, because there are sounds coming from the stepper motors. I have looked at G-Codes, but I do not know if that is the right route to go.

Is it perhaps possible to email me a short example of the code that you used?

Thanks
Michael
