Another submarine?

[IQChallenged]

In The Hunt for Red October, National Security Advisor Jeffrey Pelt says to Soviet ambassador "Andrei" "You've lost another submarine?" Pelt pretends to be incredulous that the reds have lost a second sub after all the hoopla surrounding the loss of Red October. And so it has happened to me that after only minutes (of operation) after getting up and running again I've blown another Gecko. This time it was due to my failure to provide adequate strain relief which led to a broken wire. The Y wouldn't respond to keystrokes so I started looking for the problem. A broken wire was found so I immediately powered down. After making repairs and ensuring that all the rest of my system had strain relief I rebooted. Too late. Word to the wise. Check now.

This will be the last time I get knocked out of business. I went ahead and ordered another driver. I'll send the other one off for repairs (if possible), then I'll have a backup. www.ProjectCNC.wordpress.com

This test was once put up by Marcus.

ground lead to terminal 1 (power GND) and positive lead to terminal 3. Make sure it does not read below 100KOhms, and move the positive to terminal 4, then 5, and then 6.

Now move ground lead to terminal 2 (PS +), and do same test from terminals 3 to 6.

If any read below 100KOhms, and if they do it will generally read about 10 ohms or open, then the MOSFET is blown.

All of these tests show OPEN for me. I'm assuming that confirms "blown".

Apparently not. Just checked a working axis and found the same meter results.

Open is good (100K or more Ohms) unless the current sense resistors are blown open.

For what it's worth, the ancestors of the G201 were used extensively in that movie to move stuff on the models used for underwater scenes. I was invited up to Universal Studios to see our drives in action while they filmed waterless underwater scenes (water got added later with computer graphics). The submarine models were about 12' long.

I was told the movie was to be called "The Hunt For Red October", which of course at the time meant nothing to me.:-)

Cool! Totally cool!

"Open is good (100K or more Ohms) unless the current sense resistors are blown open."

Do you have some meter values that would reveal the problem?
