what is the model of the controller. Can you give some details. The controller is really more important than the machine when it comes to posts. Don't get me wrong you need to know what the machine does but the controller has the biggest impact. We may be able to help you out but you may want to contact siemmens directly and as a application engineer. They will help the most.
If you have the manuals I will sudgest posting the error number and error definition that is in the manual. Someone with experience with this issue might ring a bell with the error you are getting.
In my experience with issues like this I would say try to fix the program by hand 1st and get it working on the machine. Once you have a working program then you can adjust the post to output that way. It saves time in trouble shooting.
