The A150 is too small to mount the rotary—you need at least an A250, but there were no longer any of the midsize units available by the time I hit the kickstarter and I didn't have the space for the A350, so I opted for the smallest model.

Embarassingly, I've used it mostly as a 3D printer. The blue diode laser originally shipped with the unit is a decent etcher but too weak to cut through anything very thick (best I've heard of anyone managing was 1/4" of wood, and that took a lot of passes and patience on their part), and it has some limitations on what materials it will handle (I'd have to scour the forum for details, because it's been a while). I didn't buy the more powerful laser that later became available as an add-on. Unless their software has improved a lot since the last version I downloaded, you'll need 3rd party software to make the most of it.

I never actually tried milling with it because of potential dust removal issues, but according to reports it once again suffers here from being a compromise device with limited software. The frame isn't quite as rigid as a dedicated CNC, the bits are Dremel-sized and a bit fragile due to that, and the provided software I have won't, for instance, handle what should be simple tasks like drilling all-vertical holes or doing multiple passes with different-sized bits. Unlike the laser, I can't recall any reports of anyone using alternative CAM software for the CNC, but it's been a couple of years since I last looked.

In the end it's kind of like a Swiss Army knife: great if you have limited space (my issue) and just want to try stuff out, but if you can manage it you're better off with dedicated machines for each function.
