I have received my shapeoko 3 xxl and assembled it. It did notice a rather significant bur on the end of and extrusion (looked like it had been dropped but I didn’t drop it. The packaging was not damaged): AFTER I pushed on the right Y carrier whereupon I also noticed 2 nicks in 2 wheels that ride on the extrusion.
I am experiencing inconsistent depth of cut on my first projects.
