Hi everyone, Eric, Joe, Adam, and I worked on the eNSR tonight. We found a lot of things:
- The "I" beam that carries the motor is shorter than expected, so when the bolts connecting it to the ring are torqued down, the whole eNSR ring warps into an oval and jams the ring. Adam is picking up shims tomorrow that we'll cut up and use to un-oval-ify the ring. - The software that configures the VESC controller board is a nightmare. Eric and I tweaked some mystery settings that seems to speed up the motor, which causes everything to work better. - We ran the eNSR about 20 times - with the wave spring, without the spring, etc., and it never failed. - We ran 3 full system tests with nosecone, recovery system. All worked as expected. We'll probably do some more testing tomorrow evening, but we now feel confident that the eNSR will do what we want it to do. See you tomorrow night!
