This is on the inside of the magwell. Both prints have weak under the mag release cut outs. The Middleton schnitzel has holes in it that didn’t show/or were missed in the slice. The picture on the left is unseenkillers remix of the schnitzel. The picture on the right is the Middleton. I followed the read me except I did 100 percent aligned rectilinear on one, and 99 gyroid on the other. Also used metallic polylite pla(don’t intend on using it, just testing). Running it at 60 gyroid right now to see if that’s the issue. I’ve calibrated polylite pla pro already. Never calibrated the metallic kind. Could that be it?
