Laser Engraver (Or 3D Printer) Controller Box

thingiverse

I used a 3D printer controller board with one blown transistor to drive my laser engraver and wanted to house the controller, which had been previously exposed. My goals for the enclosure were to house the controller itself, power supplies that provided the necessary voltage - 12 V and 5V - and a ground distribution block, as well as a relay board to easily switch large loads such as fans and LEDs. It also needed to accommodate the LCD controller and create a clean look adjacent to the laser shielding box. Detailed design notes and build instructions including components can be found on my blog post about the new controller box at: http://www.candlercustoms.com/laser-engraver-or-3d-printer-controller-with-relay-and-power-supply/ SideNote: The OctoPrint Controller with a touchscreen on top of the controller from this post is also available here: https://www.thingiverse.com/thing:2316679 It's extremely useful as well. I hope you all like my new box. It's taken a lot of work, but I think it was worth every effort.
