S1. Ran a job perfectly.

Now it won't stop running that job. How do you clear the cache of the machine so that I can send the next project?

I have powered down. I have E-Stopped. I have saved/loaded the new file, still processes the old one. I have opened XCS on a blank canvas, recreated the engraving, and when I click process- it still sends the old file. 

How do we clear what is in the pipeline to the machine?

@xTool - Please look into this- this is a big deal for me.
