My existing installation concists of: Sherline Mill using 1.8Deg per step motors driven from a XYLOTEX board operating in 1/8th step mode resulting in 32,000 steps per inch. CNCpro is the operating program on an old win 98 machine in DOS mode.

Have a Pentium 4, 2.53 Mhz Win XP Pro machine with Mach3 installed. Have only changed the Parallel port cable from the DOS machine to the Pentium.

Have set up the step/direction signals to Pins 2,3  4,5  and 6,7 for the x,y,z axis. and have followed the tutorial video.

The Pentium machine shows LPT-1 address as both 0378-037F and 0778--077F with no option for selecting either with
"Automatic Settings" checked. It is a Re-Furb machine with a Microsoft printer driver installed and no printer.

Problem is - I am unable to make the motors run.

What do you recon is the problem or my overxsight?

Thanks,

Don Carlson

Try to use the SherLine mode on the ports and pins page and if it is still not working post your xml and I will see if I can fine the problem.
Thank you

Brian: Problem was E stop not set correctly. As I do not have any stops inatalled I ignored that section. ( should have listened to the fine print!!)
With the exixting 1/8 th step driver board I had to set the step per inch to 32,000 to get correct calibration.
All works fine now.
The 1/2 step sherline does not seem to have any effect.
thanks, Don
