It’s a valid point for the commercial product, but on the other hand, I’m guessing that they types of people who buy 3d printers, are also the types of people who already have computers coming out their ears. That describes me – I have several up in the attic, laptops and desktops. The last thing I really want is another full blown computer to deal with, especially when the BeagleBone Black is about $50 to $55.
The Beaglebone video linked above (second post – the one about the “cat [who] does some awesome stuff”) really appeals to me. I could take down the iMac currently hooked up to the mini, put it back in the attic where it belongs, and give up all the shuffling back and forth between my nice speedy dual monitor linux box where I do most of this type of work and the computer attached to the mini on which I do absolutely nothing else. There’d be no need to transfer files over the network, then load them up on the computer dedicated to the mini, and then press print. Instead, I’d just press print. When I hear the printer start the print after wiping and leveling, I’d go check on it – maybe keep a small 7" tablet near the printer for canceling the print, and regain a bunch of desk space.
Probably what I’ll do is try out octoprint first, running it on the computer connected to the printer. If that seems convenient, I’ll go for it. The BB Black is so cheap I’d have no excuse not to do it.
