Hi Ive ordered the components to build a 5x10 table and downloaded a trial of Sheet Cam.How can I follow the tutorials and keep the work window open at the same time? 
It depends on how big your monitor is. If you have a large monitor you can resize both the SheetCam window and the help window so both fit on the screen at the same time. Another alternative is to resize so they overlap then click on whichever one you want to see.
Thanks much. It works and I can start using Sheet Cam for practice at least.Still waiting for my gantry from Precision Plasma and my electronics from CandCNC.
