To save you hours and hours of meticulous cataloguing by precisely measuring each of your bits’ dimensions, you can download our extensive Inventables tool library for Fusion 360 here. They are definitely recommended – you can purchase them in their official shop. They also have colored depth collars which will not only make your tool programming process a little easier, but it’s also much easier to identify and organize them. Inventables offers a wide range of full carbide bits with 1/8″ and 1/4″ shanks – that means they’re high quality and they’ll fit your router spindle.

Other people have asked about GrblGru, so if you get into it there will be a lot of interest in how you make out.Here’s where you’ll really be glad you stumbled across this article. It binds with OpenBuildsCad, so you can send right from the design page.

I liked Candle - clean,works well with grbl Grbl Panel - also clean, a little shaky sometimes OpenBuilds Control - I think this one is worth some additional time, but it seems like every other time I try it it balks. If you’re looking for alternatives to UGS, I tried some others that were interesting. But, GrblGru is definitely on my list of down-the-road retries. UGS is one of the most popular senders, there is a ton of user support, and it’s updated regularly. I find that UGS handles Fusion 360 files very well for the most part, and I learned how to get around some of its foibles, so I didn’t go back. I like the probing and curved stock support. I did try GrblGru early on, and while it is an amazing group of tools, and can do some things others can’t, I found the interface a little crowded. UGS also doesn’t like tool numbers above, I think, 200, so deselect Output Tool Number if you have high tool numbers. And if you use Universal G-Code Sender you should deselect a couple of defaults in the F360 Post Process window - deselect G28 Safe Retracts, which can drag your cutter, and Output M6, which UGS does not support and will choke on.

When you generate your gcode in F360 make sure you select the grbl post. Winstoy Moy, both on his own and as a Carbide 3D spokesman, has good YouTube videos for setting speeds and feeds in common materials, and good recommendations for Fusion toolpaths to use.

are more flexible than production machines and therefore cannot be pushed as hard. ‘Hobbyist’ machines like the LongMill, Shapeoko, X-Carve, etc. Make sure when you add new tools to the tool library that you assign speeds and feeds that are appropriate for the cutter, and that take into account the low power of the router and the rigidity of the machine. There’s really nothing specific to the LongMill you need to set up to get good results.
