Well, I'm using the second parallel port, pins 8 & 9 and am having no issues getting the 5 VDC showing when plugged directly into the DB25.
However, when I run it through the cnc4pc C10 card and out, then check the voltage, I get a -2.7 volts!?
I've loaded a couple different images and can see the voltage change when straight out of the pp so I think that would work and forego the C10 all together, but I'd really like to use the C10 to get the extra inputs, etc. (That's the reason for buying it).
I went ahead and connected to the TB6560 3A Driver Board just to see if the small voltage changes were enough to get the electromagnet moving.
No joy unless I have the board set for 1.9 amps, then the rod just stays extended, i.e., activated. I reconfigured the TB6560 3A Driver Board's switches, backing it down to 1.6 amps (rod stays in) and have begun various iterations with the other switches. After a couple of hours of trial & error, it still doesn't respond.
Gonna try with the C10 tomorrow. For those of you that do have the C10, I will say that I have the 2-9 outputs common set to 5vdc as recommended by their literature. That's the only way I was seeing any changes in voltage. If I have it set to GND, I see nothing.
Anyway, wasn't sure if I needed to go to another thread.
