I don't know when people should do a group buy. There need to be at least a few simple changes to the control section before a group purchase.
PI loop results so far! It looks sort of similar to the previous graph, but check out the scale! This one doesn't overshoot, and gets there WAY faster! It takes about 0.005 seconds to make current match perfectly with throttle if you want the throttle to change from 0 to 50 (on a scale of 0 to 500). Each tick mark on the x-axis is 1/4000 of a second.
This would definitely NOT be granny mode. It should get you to 500 amps without overshoot (I think, there is no safe way to test it without destroying my motor) in 0.05 seconds. hehe. That's disturbing.
Ignore the y-axis scale. It's a long story. Basically it should say up to 50 amps where the graph levels off, but I didn't feel like changing it.
