Re: [CAD_CAM_EDM_DRO] Need help with program setup.

Hi Norm,

I've only briefly examined Rigotti's router driver hardware (the
manual), and I see that it is unipolar. How have you connected you
motors? Did you have to cable them up yourself? If the CNC package is
similar, you'll have to get the 4 phases of the motors connected
correctly, or they won't run!

I'd suggest you divide the problem. A 'scope can be used to examine the
step and direction signals generated by the software.

A 555 timer or function generator can be used to generate square waves
to drive the driver board. "Other" step/dir software and hardware can
be used to "test out" what you have.

Is this controller a true "Windoz" program? Or are you trying to run it
in a DOS box? If it's really a DOS program, like most other DOS
controller programs, it probably WON'T run correctly in a DOS window.
Exit to "DOS" mode, and attempt to run it from there. Windoz will
otherwise be generating interrupts and slicing up the processor's time,
and driving the stepper driver crazy!
