Are you surfacing your STOCK MDF wasteboard -Or a secondary top sheet?
I like to add a topper.
FYI: 1.5" of the Y travel is out the front of the machine so do a pre -flight jog test to make sure you dont hit a limit.
For jobs like this, I suggest using the Top Left as the origin.
In the Tool Library Click: ADD TOOL
Then Double click on the Green Box (#900 in the example).
Click OK when your done creating the New tool.
CC is currently set to 32" max, most likely for safety to keep people from driving into the sides.
