Greetings to PCW; I have a 2nd apparent failure of a 5i25, affecting the same p3-15 pin. So I am suspecting I have a bad BoB or home rolled cable.
I have a perfectly good 4.77 volts at the BoB's input, which does go to ground if I touch the wire to the machine frame, but it is not getting thru the BoB and the 5i25 to motion.probe-input. How hard is it to setup a 3rd port, using the parport in the computer, so I could move the cable to the parport long enough to verify it is, or isn't, the 5i25. Unlike the first time when I thought I had blown that pin on the 5i25 because there wasn't a solid ground on the machine frame, this time there is zero volts dc on the machine frame, and less than 1 millivolt of AC with the motors all moving, So I do have a good ground now. And I have cable and connectors enough to make a new cable. And I've another BoB because I bought two for the Sheldon. So somewhere in this briarpatch is a fix. Changing the BoB would be a PIMA because while the old on is pretty much straight thru, the 2 new ones I have are hopelessly scrambled. Is that parport tester in the docs standalone? If yes, that should sort this quite a bit faster. Just move the cable to the parport and test away. Things to check other than what I just listed? That teflon rod, with a piece of 10 gauge copper for the probe is together and looks like it will work well with my hole finder routine. But first I need to actually make a G38.2 work. Thanks Peter.
