3D relief carving

Post by derrak » Wed Jun 24, 2015 6:24 am

My first 3D relief project with Shapeoko 3 (SN#75) and ChiliPepper. My wife and I were scanned at our local science museum, OMSI, by a company called JoeScan, who makes laser scanners mainly for the logging industry. I downloaded the stl, cleaned it up in Blender then imported it into MeshCam where the gcode was generated. Overall runtime was about 5.75 hours carving into a chunk of walnut. The height of the cut is 22CM, depth ~2CM.
The tool change, from a .25" upcut to a .125" ball went very well in ChiliPepper with the aide of a touchplate.

Finished output:

Roughing pass output:

For scale:

I have since cleaned it up with a Dremel with flap wheels, but haven't had a chance to finish it yet. I may post an update when it's complete.

Looks neat. Reminds me of Han Solo.

This is pretty cool. I use MeshCAM myself, and could never figure out how to do tool changes. However, I also use UGS. What is your method for doing tool changes?

Not sure how meshcam works but I just export the Gcode code for one tool, such as engraving, in a file, let the file run, hit the return to zero, raise the spindle and change tools. Rezero manually and load the profile file and run it.

We should make a group of Portland area Shapeokos.

Hmm, OK. I just discovered one of the reasons I'm having such trouble with this is that it appears UGS does not recognize the tool change command, and just moves on. I just started trying ChiliPeppr, which pauses at the tool change command, throws up a window, and lets you swap the bit.

The OTHER tidbit I realized (a little late unfortunately) is that the plastic collars on the bits are so you can put them into the chuck at the same depth. :oops:

These two pieces were the missing links that caused me to give up on tool changes. Hopefully some other noob can benefit from my eureka. :P

I'd be up for a Portland Shapeoko group!
Shapeoko 3, not yet running anything other than makercam... I have many questions and I think I want to move onto meshcam or something else, Want to bounce some questions off people using meshcam.

Good job your first carving! To clean it up, I would recommend a smaller stepover. I used a 40% (.05 mm) stepover for my first 3d carving and it turned out pretty decent. It will take longer of course, but the result will be well worth it.
