Hi Will,
Thanks for the info on Arduino - looks like some interesting possibilities
there. I didn't realize that Arduino had several different boards available. I
may be able to connect one or more boards to a DB25 parallel connector to
control my HobbyCNC micro-stepping driver board.
Thanks,
Hi Dave,
Thanks for the info. I do agree that these solutions are better than what I had
intended to do, but they are a bit expensive for the average hobbyist. The
controlling CNC applications are still PC based but can run under "Parallels"
on the Mac since the controllers offload the realtime

Hello,
Long time lurker making first post here. You could use an Arduino and do the
real time pulse generation stuff on that. Then just write a macruby app that
serialises the commands and feeds them to the Arduino which interprets them and
flips the necessary IO pins on and off. It's years sin
Indeed, I can only agree that USB based parallel port adapters have
very shitty timing, in no small part due to USB itself. You cannot do
motion control over USB->PP like you could straight to the parallel
port on Windows (which wasn't that great to begin with), the motion
control part needs to be
Hi Bob,
You don't really say what your final goal is so this may not suit your purpose.
PC based CNC controllers are suck in the dark ages - not only for the GUI they
present but in how they control the steppers via the printer port. They rely
on low level Window's drivers to generate accurate
