So I finally got tired of the Dewalt Router and it’s wobble on the axis and the need to replace brushes all the time and installed a nice water cooled spindle. I figured 800W is plenty for what I use it for…
Also got a matching 65MM diameter HD spindle mount from Carbide3D… that thing is SOLID and it looks like no tramming needed kind of precision.
After I installed everything, made some mistakes, ordered some replacement parts … time to make some test cuts.
Step 1: Basic 2D “hello world” kind of cut
Simple Carbide3D logo, drawn in Carbide Create and cut with one of my favorites, a 2mm downcut endmill
Result: Very nice. The pockets are SMOOTH. No tramming needed. Love the spindle (quiet!) love the 65MM HD Mount
Gcode: cclogo.nc (86.5 KB)
Step 2: Basic 3D cut from a STL file
Grab an STL from thingiverse (https://www.thingiverse.com/thing:50851), add spindle support to gcode converter, convert to gcode (https://fenrus75.github.io/FenrusCNCtools/stl2nc/stl2nc.html of course) and cut out of 5x5 basewood, while cheaping on time with a 1/8" bit and too big stepover. Bad mistake. Basewood is too stringly to get nice 3D cuts… but that is for next time
Gcode: ripple_4_130210h.stl (1).nc (2.0 MB)
Step 3: it’s Friday night
So it’s Friday night, and I’m sure everyone else by now is also asking themselves: This was boring. Can we cut the 2D gcode from step 1 right on top of these 3D ripples?
(well maybe you don’t. But I did. It’s been a long week at work)
The answer is: Yes you can. Maybe you shouldn’t, but you can.
All kidding aside, in 3D vector tool path @ads wondered if one could use 2D toolpaths to cut roads into 3D landscapes and well, yes you should be able to.
It’s just a matter of modulating the Z elements of the Gcode to the underlying 3D model (bla bla more digital software gunk here).
For example, the gcode from step 1 above, after modulation, looks like this: cclogo2.nc (2.5 MB)
This will work for any STL file, overlaying any gcode that carbide create will generate…
