I got one of those printers as my fourth printer, because my other three weren't big enough. I've got it configured with two different nozzle sizes and a couple different types and colors of filament, so it's always ready to print "whatever". It's nice to be able to print panels and boxes with the labels already in them, with supports that cleanly break away because they're a different chemistry. For a custom LED display that takes advantage of these features, see Clough42's https://www.youtube.com/watch?v=7nWGfz3__3A Those more expensive printers also allow you to print with more exotic filaments (so-called "engineering" plastics) like TPU, Polycarbonate, ASA, nylons, PEEK, etc. >> Oh. So, you can't tweek anything once you've built the file? The file is just too big and it's too difficult to map the bazillion of tiny things its commanding to what you get in the real world, unlike programming a CNC machine. The file is so big, in fact, that most printers support a compressed binary format *just* to get it to the printer faster. Example: I just printed a small L-shaped bracket for my wire stripper (a stop so I'd strip a consistent amount off). The raw ascii gcode without comments was 1,522 commands. The biggest gcode I still have on disk is 132 MB. The *smallest* gcode still on my printer is 82k of compressed binary. and that was for a plain cylinder that took 26 seconds to print. So while you can (and I have) manually edit gcode, you really don't want to. It's like choosing to hack the postscript being sent to your printer instead of just fixing that typo in the word processor instead. And no, most 3D printers do not support complex gcode constructs like looping or conditionals, so manually crafting gcode for them is tedious. Even for custom hacks you end up writing software to generate the gcode for you.
