Had an almost complete board until I realized that USB wouldn't have worked because it didn't have an uninteruppted ground plane. Same goes for CAN. Also need to redo the layout for the stepper motor so that traces are short as possible.

Relayedout the whole board and got a layout im happy with and began the routing process. I had to change the diodes since they didn't have a high enough current rating to handle the stepper motor. I still have a couple more signal traces to route and then I can put in the powerplanes.

Finished the initial layout of the board. Still need to rearrange some components to fit the M.2 card on the board. I think I picked the wrong connector for the M.2 card. Need to go back and fix that. Also, the enable pins I think have too many resistors. I might drop the pull down resistors on the enable pins for the stepper motor. Also, I upgraded to Kicad 6 as I needed the latest version to view the PCB file and we can set custom design rules for future PCBs.
