Could someone help me make gcode of this design?

Could someone help me make gcode of this design? I have an STL file with something like 4100 triangles in it. I was hoping to carve it into a piece of wood, but I keep running out out of memory and it kills my laptop hitting the swap space. If you know of a free bit of software that can handle that much detail, please mention that too.

Where’s the stl file? Is it something you don’t want public?

Not too public. It is a late mother’s day present.

I will probably make the file public Next month, but not this month.

You can send it to me and I can try to get something to work. I’m always up for something fun!

OK, Marc. I sent you an email. It has a PNG and a SCAD file instead of an STL though. It turns out that OpenSCAD made a massive STL of almost 500MB. No wonder PyCAM was choking on it.

You now have a ZIP file with a resaved STL file in it waiting for you in your email. Thanks again for the help.

I am trying out dmap2gcode and it seems to work OK for height maps like this one. It is definitely a keeper.

What size bit are you planning on using?
1/8"?

1/8" bit. 0.74in thick wood. 7.2 in tall and 10 in wide. Poplar.

Endmill or Ballmill?

it is not flat on the end, so I guess it would be ballmill

You could try working with Fusion360. It will produce Gcode, after you import the STL. If you like I can try converting the STL to code.

Also, I’ve found meshcam to be amazing for 3d milling. You can get a fully functional trial from them and it pretty much walks you through the entire process.
