Bug Hunting
- MSIM failed again after target run with newly generated targets.
- Positioner 41 had a calculated angle of 418
- We found a new case for Hrands state machine but it is not easy to determine reality without longer history. (Positioner may be stuck or overshooting massively, can be the same).
- Code that handles large angles beyond mmap values worked but then 0 steps commanded triggered a search algorithm for looking which 1 step move brings us closer to the target.
- This search then needs to lookup mmap and fails because it can't find it.
- Hrand will implement a error catch setting step sizes to 0.
- The region issue will be handled by ignoring the positioner for that run.
-
- From the test data several positioners show stickiness:
- pid 53 has clear interaction of flex print with neighbour
