Hello! Sorry, my life has gotten really busy, and I haven't been on here at all. But I am doing some interesting things for a company I work for at home. Even NASA is interested in one of the things they are doing.

Duncan, the temperature protection works as follows:

if around 75 degreesC, maximum motor amps are 7/8*500.
If around 85 degreesC, maximum motor amps are 0/8*500.

And it smoothly goes from 7/8 down to 0/8 as the temperature climbs from 75 up to 85. So, that definitely sounds like what was happening to you, duncan. You might need a heat sink with fans.

Flores, could you post a picture? I don't even remember anymore, but I bet seeing it would jog my memory. If I were to guess, I'd say it's the same order for B+, M-, B- as the 500amp version. B+ is next to the capacitors, then M-, then B-. Could you also take a picture of the wires? Did you build this or did I?

What would be involved from a software perspective to implement an idle function in the revolt?
I don't think it would be that bad. That's my guess at least.
