Made some progress. Used a 32in card table with a piece of plywood for the top. I ran out of pipe so I printed the old legs and used them instead, and spilled some ABS cement while attaching them (gives it character). Today I mostly did wiring and I think I finally got it all working, so look forward to some more pics tomorrow!
Regarding using Repetier-Host, I’m very familiar with using it for my 3d printer, but I’ve never used it for CNC. Do I need to somehow invert my models or is there a way to set it to just cut around an object?
Also what is the easiest way to cut the surface level? Thanks!
