+### Exporting drill hole
+Exporting drill holes is a bit weird in kicad. You need to press some other buttons to do that. In the export menu I clicked the generate drill holes button.

 ## Using modsProject to use the machine
 We use modsproject.org to send our designs to the machine. The website uses webserial to communicate to the device so you need chrome or any chromium based browsers to use this website. Otherwise it won't work.

+## Issues when milling
+When milling some of the traces where too close and modsproject combined all these traces into one. Henk helped me and set the tool diameter a bit lower so these traces would get cut out. Next time in KiCad I need to increase the spacing a a bit to account for sloped traces. Because KiCad doesn't account for it well.

+So I halved the the cutting image because I didn't wanna re cut everything again but then It also broke some traces that it wasn't supposed to cut.
