I received my Alunar Q300 with in 4 days. It was well packed in a heavy duty box.
I unpacked and assembled it in a little over 1/2 hour. It is about 95% assembled right out of the box.
It came with all the tools you need to assemble and or service it, a few spare parts and a small roll of filament.
There are three 3d printed parts on the printer, and the flies to print them are on the sd card if you need to replace them.
I found no instructions on the USB card. I watch the 3d printing nerd of you tube for instructions.
when I printed the cat file it ended up with out a head. Not sure what happened.
The layers that printed looked great.
I downloaded another cat and printed it. The quality was very good, layers were as good as I have seen.
I used Simplify3D 4.0 as a slicer with the default settings for the Aluanr Q300.
I saw no zits or stringing on the cat I printed.
The construction was very clean and solid, The electronics are in a separate very well built metal case with a nice LCD display.
. In my opinion, this is a very well thought out and designed printer.
I would definitely recommend the Alunar Q300 to anyone. It is a great printer for the price and easy to use.
