Hi Craig,
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.
Also wanted to add that when using a toolpath zero located at the center of the stock/work area, coordinates of geometry still reference the lower lefthand corner. Makes it really hard to actually center anything. would be better if setting a rectangle’s center to be (0,0) moved it to the toolpath zero.
