And here's another picture showing overall detail of the first layer.

Hi, guys. We recently received UM2 for our project and I was excited to have an opportunity to get involved into 3D printing which is awesome indeed! My project is an enclosure for a tablet. The print is quite large. 220x165x120mm. Height is not a problem, nor is the length of the object. I have a weird problem of under extruding that occurs only in one corner when making first layer, which actually is non-regulated, top-right hand corner. I need that surface to be smooth as a mirror and just of this behavior, the print is not perfect at all. I am attaching 2 pictures that are showing the problem. Another problem is with scratches all over the print, that I have no idea how to fix, although I tried to fine tune Z Hop. Settings that I use at this moment: Filament - Atomic bright white 2.85mm Nozzle - Olsson block mounted - 0.6mm First and the rest layers - 0.3mm Speed - 30mm Bottom layer speed - 25mm Shell - 1.2mm Botto/Top thickness - 0.9mm Nozzle temp 230C Bed temp 55C I'd appreciate if you could help me identify the problem.
