I have not been able to get the Job visualizer to work "View Job". When I load in a job and hit View job it just gives me an error. I am using a post processor of GRBL Inches. Should that matter? Also is there a way to visualize the job off the SD card? Or would I need to load in the code from my computer? Secondly when I used to use the Openbuilds control there was a feature to "Check size" of the job you are about to run and it would move around the perimeter of the cut area. Is this possible with the cnc3d? Thanks, Eric
