I guess that's my next task. The plastic mount I had made for the motor shaft to encoder will work ... but I need to fab up a bit of a mount to take the weight of the encoder and some way of shimming things so that they are basically level/aligned.

After the run-rotor-test ... what do I do with the results? I'm sure that there a command to set the rotor constant, but I don't think I have seen it as yet.

BTW - is there a way to list the present settings? If I had done that, I would have caught the typo on k 3884 instead of p 3884.

Sorry I did not respond last night. I was trying to edit video .. load drivers for obsolete phones .. trying to zoom a window of gopro video ... not a successful evening!
A bit of confusion, and some frustration:
- run-pi-test runs for 45 - 50 seconds, then outputs all values from 62 up to 19964

- pi-ratio 62
- run-pi-test - same results

- p 3844
- i 62
- run-rotor-test

no rotation. Nothing appears to happen.

Cycle power, go through a few trials ... and decide to take a video asking you guys to show me the dumb thing I'm doing wrong.

Start the cideo by going through the setup.
- High voltage pack - 125.5V
- Low voltage battery - 13.1V
- Throttle - 4.90V - a bit high perhaps


Adjust throttle to 2.48V
Power up
Record run-through

pi-ration 62
run-pi-test - it works
output is one number - 05704
i divides out to 92

p 5704
i 92
run-rotor-test

it takes a few minutes to rotate, then puts out 0's as the speeds.

So I got back to where I left of yesterday (but I know now that I should check the throttle position before starting any testing!!)

So I need to make a mount for my encoder.

I began the process, but it took longer than the evening that was left.

Video will be posted, if and when I get some time ...
