Has anyone experienced situation where a motor would lock up when running a program with multiple myblocks (and nested myblocks)? We're experiencing this problem with our robot's 3rd motor when we run a master program (where all our missions are in one program), which we don't see when running the missions individually. Does anyone have any suggestions? Will activation of the 3rd motor on a separate track fix this? Has anyone found reasons to stay away from using master programs?
