After all the swarf machining the Y-axis motor mounts, I decided to hook up the flood coolant system for the CNC mill as the next part I was going to machine was the X-axis motor mount, and that would involve a huge amount of material removal, so chip evacuation was a big concern.

Thankfully this huge mess was expected, and the CNC is fully enclosed! Don't worry, that's just a reflection of the computer's monitor; it's not actually in the enclosure. :)

Oh hey, look - I found an angle where I can kinda see the work piece even.

The aftermath of a several hour machining operation was pretty messy.

Unfortunately the part was a failure due to me entering the incorrect tool diameter into the CAM for the toolpath, causing all the features on the part to be removed. Oops. Another lesson learnt.
