I am very impressed so far as well.
New Matter responded very promptly to a comment I left on Indiegogo about software features...
"Hi Kraig! We're working as fast as we can to get a number of features implemented, one of them being an on/off supports feature. Thanks so much for your patience!"

Once we can configure support material, and maybe temperature, it will be awesome.
There are a few things to improve in the web slicer interface. The scaling and rotation I am not too clear on. I can only seem to do adjustments in large angles. SO uploading my own files might not be 100% predictable yet.

I actually like the calibration method, but I am a little concerned about the "wipe" the nozzle does. I am having a hard time completely removing that thin scraping of filament, and it performs that function in the same place each time, so I'm afraid after a while it might interfere somehow.

But the printer is really beautiful. I got the white one.
