---++ 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 ---++Cold Test EM RAIL LOG | *COBRA* | *RAIL* | *Board* | *INVERTED* | *Current* | *Performance* | | | *POSITION* | *POSITION* | *MSIM ID* | *SNR@iter[date]* | | EM1 121 | 01 | 01| no | 1 |BROKEN @ [15_03_28_22_51_02_TargetRun] prev.
