Great machine, very poor slicer
By now it is 4* although it is only 2 days I am using the machine. From engineering stand point the Snapmaker U1 is just a jewel, perfectly assamble, high quality in the parts and of course, the winner when printing multicolor and/or multimaterial. The weakest point is the Snapmaker Orca, the slicer. This software is not ready and use to shut down, get blocked and have many issues to communicate with the Snapmaker U1. There is not alternative to send files by wireless since Orca Slicer and others cannot do it. Once Snapmaker Orce is ready and working, I will add the 5th star.
