Re: M57-102 < - - - - > PC

I worked at getting the motor turnig today, but to no avail. The
problem you indicate here. I had visions of making the parallel port
control a more powerful source. I have only about 1.5 volts with the
step port high. Looks like I should search for the buffer...
Thanks for all the help
Randy
