What version of EMC2 are you running? The recent ones will display soft limits as dashed red lines on the backplot, which will allow you to see where they lie in relation to your toolpaths.
Some other things to check:
Be sure to home your machine before loading your file, even if you don't have home switches. Otherwise EMC2 may think the machine is at a different position than it actually is.
Verify that you're using the same units in cambam as in EMC2 (inch/metric).
If neither of these are the problem, please post your ini and gcode files and we may be able to help.
