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.
