It's ok ... if you can get it leveled , if you enclose it, if you use a mirror instead of the stock (warped) bed, and if you tune your settings (which take time), you should be able to get decent prints... I wasn't able to get anything other than pla to print on this, and so I'm sending it back. Very sad, the print volume was so promising! I may try the M608 or it's newer iterations later on. Maybe by generation 3 Alunar will have it right. Until then I'll continue my quest elsewhere.
