>The stepper board kit and DeskNC has arrived OK, I am working this weekend,

so I won't have much time on my hands until Tuesday, I installed DeskNC on
this pentium 400 and had a quick look around it, It looks a nice little
program, I tried to get it to run my Compucut files (PR format) but without
success ( will it do this or will I have to convert these files to G code
format) as I say I did not have much time to experiment with it.

Desknc needs G code files
Can you send me a sample of your Pr format?

> If I can I want to get DeskNC to run the Compucut unipolar board,

this would give me a chance to familiarise myself with DeskNC before I
change over to the bipolar chopper board setup, and make the change a bit
smoother, I know the Compucut port setting for XYZ is 888 The only
other information that I have is

In desknc set X step bit to 3
x direction to 2
y step to 5
y dir to 4
