Hi all; Today is "CNC Machine Day", and I've spent over 3 hours trying to get a 5i25/7i76 combo working.
1) jumpers verified on 5i25, so that it supplies 5v to the 7i76; 2) both yellow LEDS on the 7i76 light. 3) Field power, separate 12v power supply. 4) 5i25 has sticker on back saying it has 7i76x2.bit (or very close) installed. Symptoms. Nothing happens. - No stepper movement. In pncconf, no movement when testing axes. digital stepper drives have green LED lit (Leadshine DM856) Motors do not power up; they are as cold as the machine. Leaving the enable lines unconnected (as per documentation) or tying them high/low does nothing. - Trying Ed's test at http://softsolder.com/2013/06/18/mesa-5i25-7i76-first-light/ does nothing. (using his wiring in the picture, but with an old needle volt meter, and then a digital meter - would have expected the analogue needle to at least quiver off of 0.0v) - running halcmd show pin for an input pin does not change anything when the pin is tied to field ground, or field v+. - LinuxCNC - no movement, no ability to set or read a HAL output pins via the hal commands, and watching pins does nothing. Took the parallel cable off of my working machine (5i25 driving a g540) to see if something happened to the cable currently on this machine. No change. I'm obviously doing something idiotic. Maybe I'll go and take the dog for a long walk. But, I did not expect to have nothing coming in. So, any thoughts as to what I have missed? I might have to just go back and work on my KX1, now that I've been given some help on THAT one by you guys this week...
