Rayhager,
Could you post the code that is giving you the error message. You may need to tweak your post processor for sheet cam. Myself or someone else here may be able to help you with that.
As far as the reverse run, have you tried it like this? Load a program, run for a bit until you get to a point you want to reverse the run. Press feedhold, cycle stop, reverse run, cycle start. I will try this on my machine in a bit.
