HAM6-ISI - Initial In-Chamber Testing

I ran a Local static test on HAM6-ISI to make sure sensor/actuator wiring is correct throughout the chain.

Results are attached. We drove 1000 counts on each actuator, and looked at the cross-couplings. Main cross-couplings (red) show that V2 actuator needs to have its cable flipped. This is a quick fix that will be performed tomorrow.

 

It also seem like the responses are not as consistant between corners as we would like them to. Rubbing cable(s) could be the reason.
