I really like the RepRap iTopie, so have started to build one. I didn’t build my MPCNC with enough Y-axis to cut the larger parts of the frame in one operation, though, so have split each large part of the frame into two pieces. I could have done a jig or some alignment pins and moved the workpiece for two operations, but I’m only building one, so decided to try it this way.
The vertical portion of the frame is symmetrical, so I’m cutting it as two identical pieces, flipping one, and joining them with a big lap joint. The horizontal portion is not symmetrical, and has pockets along its face, so I am going to do it with two dovetail joints. I’ve only cut the vertical portion so far.
I have done absolutely zero woodworking before, so it will be interesting to see how (if) this works out.
