I have been a machinist for most of my life, I put getting a printer off until about 3 yrs ago .. I was intimidated by learning something new.. After I jumped in I actually was surprised as to how simple it really is.. Mainly I was intimidated by my own experience.. If I crash a mill with a .750" carbide end mill in it , thats a $75 crash minimum if it only takes out the tool.. Then theres the cost of the part that most likely was ruined in the crash.. So yeah to set up a machine that the worst things that happens when you "crash" it is you might scratch the build plate was both refreshing ,and a little underwhelming.. LOL
