Laser Engraver (Or 3D Printer) Controller Box

thingiverse

I used a 3D printer controller board with one burned up transistor to drive my laser engraver and wanted to house the controller, which had been previously exposed. My goals for the enclosure was to house the controller itself, a power supply to supply the power for the laser engraver with a 12 V and 5V and ground distribution block, and a relay board to easily switch large loads which in this case is the fans and the LEDs.  It also had to accommodate the LCD controller and make for 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 the touchscreen on top of the controller from this post can be seen here: https://www.thingiverse.com/thing:2316679 It's super useful also. Hope y'all like my new box.  It's taken a lot of work, but I think it's worth it.
