Mac + Mach3: Building Cutloom, a simple 2.5D CAM app
« on: August 18, 2026, 10:13:20 AM »
Hi all,

I've been using Mach3 on my BZT CNC router for quite a few years, with CamBam doing most of the CAM work.

Recently my old Windows laptop started becoming unreliable. I basically had two options: buy another Windows laptop mainly to keep my existing CNC workflow running, or find a good CAM alternative for my Mac.

I couldn't really find what I wanted.

There are some very capable CAM packages available, of course, but for most of my CNC work I don't need a huge CAD/CAM suite. I mostly want to import a DXF, set up some profile, pocket or drilling operations, preview the toolpaths and generate G-code.

So, being a software developer as well as a CNC hobbyist, I did the sensible thing and started building my own. :-)

It's called Cutloom, and it's a native macOS 2.5D CAM application.

Mach3 was one of the first post-processors I implemented, because that's what my own CNC runs. GRBL is supported as well, and the post-processing system is configurable so other controllers can be added without changing the CAM side.

At the moment Cutloom supports DXF import, profile, pocketing and drilling operations, toolpath preview and G-code generation. I'm continuing to add the other core 2.5D operations and features.

The public beta isn't available yet, I hope to have something available soon.

Since there are obviously a lot of experienced Mach3 and Mach4 users here, I'd be very interested in your feedback. What would you consider essential in a straightforward 2.5D CAM application? Are there things your current CAM software does that you absolutely wouldn't want to be without?

Cutloom will eventually be a commercial product, just to be transparent about that. Right now I'm mainly trying to make sure I build something genuinely useful before releasing the beta.

I've put some screenshots and information about the project here:

Happy to answer questions or share more about how it works.
