Hey guys, I've been wondering, do any of you guys use your machines for 3D milling, and if so, what software and hardware do you run. 2.5D from my understanding is only 2 axis' can move at once, while 3D can move all 3. When describing a 3,4,5 axis controller, does that mean that all of them can move at the same time? I'm searching for hardware currently and want to make sure that what I buy can support 3D milling. Specifically looking at the G540 thanks to recommendations from another thread in the electronics section. Any input is appreciated!
