Hi, as we all know, using CNC machines can be quite dangerous and finicky.
That´s why we developed an open source Speeds and Feeds calculator, which you can adapt to your specific machine. With a calculator like this one, you remove one more boundary from using a CNC. We used this post from Stepcraft as a foundation of the formulas: Milling Parameters We found the parameters to be a bit too much for our machine, so I recommend you try what your own machine can do.
I look foward to what you do with it.
