Hello, I am considering the Up Box+ and Raise3D N2+.

1. How noisy is the Up Box+? Can people sleeping next door in the same apartment or my neighbor hear it if it prints in quiet evenings?

2. I think the official filaments are in 0.5kg/roll. Do most users use the official filaments or those from other companies? Any recommendation? I guess if I use 1kg-roll, the standard holder may not be able to hold larger filaments.

3. What happen if it runs out of filament in the middle of the printing job? Will I be able to replace the filament and resume from where it left off?

4. For those who have used both Up Plus 2 and Up Box+, besides build volume, how are they compared in terms of reliability, print quality and software? I had good experience with the Up Plus 2.

5. For the Raise 3D N2/N2+, it is recommended to keep the top open when wanted to print good quality objects in PLA. For printing ABS, the top should be covered. Since the Up Box+ is closed all the time, does that mean printing PLA may not be as good as printing using ABS?

Thanks.
