Re: [CAD_CAM_EDM_DRO] Wiring Problems

Adding a little in, Chris has gotten motion with the drives when he tested
in the lab. It is when he is connecting to his target computer that he is
not getting motion. He has tried it with Master 5 and CNC Pro. Both are demo
version.

I was thinking about this problem while driving home. If I am following
correctly and it dod work hooked up in the lab it would lead me to believe
that the problem may be the parallel port on the target computer. The lab
test proves the drives, motors and power supply are all working and as far
as I am aware the only difference is how the pulses are being generated to
make the motors move. Anyone have a good test to verify the parallel port is
OK? I would likely use a logic probe or even hook some LEDs from my pins to
the +5 v line and then using one of the CNC softwares set the steps per inch
to something large like 1000. Then take steps of .001 a step at a time and
verify that the pin is toggling.

Any other ideas??

Hi all,
I'm a little new to the whole CNC scene – Tim told me to post
here and ask my questions. Anyhow, I've got two Geckodrive G201s, a
DB25 breakout board from Camtronics, a 24V, 7.5A Lambda power supply,
and two Vexta C7034-9212 2.5V, 2A steppers.
For some reason I can't seem to get any of it working right…
can someone or a group of people PLEASE help me? What software should
I be using, does anyone have a drawing/schematic of how to connect it
all, so I can confirm my connections?
Any/all help is appreciate – thanks,
