The next challenge is the enclosure. The SKR 3 is a tiny bit larger than the RAMBO 1.3L it is replacing. Just enough so that none of the standoffs in the metal box created by Lulzbot will align. The RAMBO 1.3L is 104.5mm at the widest, where the SKR 3 is 109.76mm. Too much to fudge the numbers. Additionally the standoff pattern doesn't match up.

To assist with this, I pulled the diagram PDF into Inkscape and scaled to a 1:1 mm on my canvas. Now I can draw boxes, and plan wiring with the board to scale.

I'm using the "CNC Tabbed Box Maker" to design the box and will glue the back and sides together.

I scaled the board and the drawings for the connectors and started laying out the box.

I'll laser cut it out of cardboard first then some acrylic. I plan to create a box a bit bigger than necessary, that way I can work inside with some comfort.
