There was a bug discovered in EMC. What you need to do is increase the
parameters in the files .../emc/src/emcmot/emcmot.c, and emcstepmot.c
that have the text #define xxx_TASK_STACK_SIZE in them. They are generally
2048
now, and need to be increased to 4096. There should be two lines in each
file. Then, recompile EMC and try it again.
