Help !! I have been running Mach3 for quiite awhile-Computer dumped-bought a Compaq Presario (wanted XP)with no Parallel port but I ordered a plug in parallel but this little computer has no plug ins
This is probably an old question but is there any way to run Mach3 w USB ports 

If you get the SmoothStepper it connects via USB to Mach.
