Hi,

yes now everything is working. I took a different computer and voila ! First i did use a Fujitsu Siemends Laptop - X Axis not working, now i use IBM Thinkpad - and everything is nearly fine. For Christmas holiday i want to get a cheap second hand desktop pc to get the full 5 V out of the parallel port.

Anyway - my x-axis is still sometimes losing steps. I don´t know if this is a general problem with this chinese board or if there´s a mechanical problem. But each day my machine gets better...

Good luck
Andy
