RE: [CAD_CAM_EDM_DRO] Wiring Problems

First he should make absolutely sure that the port address of
his home PC matches his software configuration file. Most software, but
not all, requires the decimal equivalent of the hexadecimal port
address. He can verify his port address by watching the pc during boot
up. The port address is usually printed to the screen at that time. It
will probably be the hexadecimal address 378H which is 888 in decimal.
But CNCPRO does use the hexadecimal port address so it should be set for
0x378 if that is what he sees during boot up.
It can also be a software configuration problem in that the software
pinout does match the driver pinout.
Next, not all cables that run from the pc port are the same. He should
verify that all pins are wire straight thru by running a continuity test
with the cable disconnected.
Last he can use the jog mode and toggle the pins on and off. I have a
little LED port tester that I made years ago to test for output. But a
logic probe is also good.

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,
-Chris Clough
