 ## generating toolpath
 
 ### Development board
-I had allot of problems developing the toolpath for milling the board. It should have been a fairly straightforward process since we were given the design. I will try to articulate my issues here: [problems with toolpath](https://fabacademy.org/2021/labs/vancouver/students/james-khan/assignments/week04/#problems-with-pocket-toolpath).

 I used [Carbide Create](https://carbide3d.com/carbidecreate/) to generate my toolpath. Our precision desktop CNC mill is the [Carbide3D Nomad 3](https://carbide3d.com/nomad/). Carbide 3D are also the makers of Carbide Create, so it was the recommended software for generating the toolpath.
