The sidecar was fine (LED's ok, and we tested voltages with multimeter, its getting 12v), we swapped it out for another sidecar just to be sure and repeated the process, checked all connections etc. Here's what's really weird: we'll run the same code multiple times, and it will do something different every time, somewhat related to what its supposed to do (i.e. sometimes delay up to 30s before driving a bit, then spitting out a tube; sometimes functioning perfectly). It's like it has a mind of its own. We're using 3 wire servo to the Jags (checked all the connections), we're really stumped. All that is left to eliminate is the power distribution board (which checks out ok via multimeter), and the Jags/connection to them, so maybe we will try swapping those out.
Could the Jags via servo cable be the issue? We have a Y cable going to each drive side and yet still sometimes you can hear it drag a CIM. My personal guess is that at least one Jag is bad, but I don't know if that could cause the other issues we are having. The students have noted that sometimes the Jags flash red when these issues arise which means there is a fault.
We'll keep working on it, no discoveries yet
