This is awesome software.
You can easily do pretty much any 2D and 3D CNC routing you care to imagine
We have build a number of CNC routed oak furniture pieces
We have also done 3D skulpted masks

You can easily enter the parameters of your cutters/knives/bits.
It is true that I have not used more expensive software, but it is also true that I feel no need for it.
We built our own machine and were leaning toward gbrl.
When we discovered this software run by an Arduino Uno, we tried it, loved it, and have not looked back
Our only wish is that it could be run on linux OS.

A bit of CNC routing of a stool leg.
