Interesting blog post on open source CAD

Here's a blog post and some new to me CAD software from the open source space travel people at Mach 30
Why We Need Professional-Level Open Source CAD

I'm not really a fan of open source CAD and this is probably why, but I know many here are.

Re: By-The-Inch Pricing of Jobs...

Not sure if it's possible to get a total inches traveled, but if I were charging, I'd go by time instead. A tool path that's all curves or lots of corners will take longer to complete due to accel/decel than a path with long straights. Depth of cut, feed rate, etc will also effect how long it takes ...

I actually have a nearby metal shop that picks up a bag of sawdust every once in a while to use for spill cleanup.

Re: Wooden Mason Jar

Meshcam should be able to do the same thing I suggested in cambam, I just don't know the terminology or how to suggest going about it. If you have a paid license I'd suggest rooting around a bit before switching.

Re: Wooden Mason Jar

I use cambam and I think this would work but it's untested. Set up a 3D contour operation with a 0 step down and a healthy roughing clearance (you prob want to measure the stock to see what that should be); copy and paste the operation as many times as needed, each time reducing the roughing clearan...

Re: Portable Precautions?

All good suggestions so far. I would definitely look into the torsion box, it will keep the whole thing more rigid if not a little more cumbersome to move. On the clamps to hold it, also seems like a good idea - you may want to look at some linear rail manufacturers and what type of clamps they prov...

Re: Project parts resource sites

Most suppliers nowadays provide 3D models as well. When designing an assembly that's often where I will start. For example McMaster, SDP/SI, Misumi and others have models of most of their inventory. I find them to be quite accurate, I've designed gear trains using models from SDP/SI, had my parts mi...

Re: 4th Axis?

4th axis has been on my wish list for a long time now. Personally though I'd like to do an indexed 4th while maintaining the existing X,Y, and Z, this would allow the spindle to have way better access than a Y, Z, A or similar.

The soundboard looks to me like homasote which should be available at your local home center.
