Design Specs for Fusion 360 Tools

I’ve been a user of the Snapmaker 2.0 A350 for a year now and have mastered laser etching and 3D printing. However, I’m only now getting into the CNC of the machine. I’ve downloaded Fusion 360 for personal use which offers 3-axis milling. Eventually I will shell out the $500 for 4-axis once I feel I know what I’m doing with the rotary attachment.

I’ve already designed a simple part to CNC in Fusion 360, but the manufacture step requires inputting tools into the tool library first. I measured the ball end tool and input it’s size. I entered 7500rpm and a 0.2mm step down as well. Beyond that, I have no idea what I’m doing with feed rate and other things.

Has anyone tried designing their own things on the Snapmakers CNC? Where’s a good resource for appropriate tooling feedrates and rpm? Is it possible to set the CNC bed on top of the 3D printing, heated bed to make a quick changeover? What offset is that? Any help is appreciated

Most of what you’re asking has been answered in several different threads on this forum.

The SM tool library is available on the SM support section of their website.

You haven’t said what material you’re trying to cnc so giving input on any speeds or step-downs is impossible. Most materials you should just have rpm at 12000. Acrylic is one of the few exceptions (but not always).

Lots of people have designed things in Fusion, tinkercad, blender, etc and then exported an stl from there. Luban doesn’t have design capability. It can only do very simple settings and toolpaths. There are a couple other programs to create toolpaths, Fusion is the main one.

It’s possible but not recommended. Some people have created some quick change beds but they’re never going to be as stable or as safe as using the cnc bed as it was designed. For light stuff you can probably get away with it. Not for the stuff I do. Use an electric screwdriver if you want speed (look on amazon for wowstick as an example)

Work origin is determined by how you’ve set it in Fusion and then set according to your work material at start of job on SM.

Couple topics to get started:


Does the fusion base subscription 3 + 1 axis milling sufficiently work for the rotary module for what most people use it for? The machining extension is a requirement for four axis simultaneous and it is an additional cost ($1600/yr): Machining Extension | Fusion 360 | Autodesk
