Pocket NC V2 - Facing 5 materials including stainless steel

This video is meant as both a reference for owners of this CNC and a demonstration for those who are considering purchasing one. As far as I&aware, there are no other videos demonstrating milling 4140 steel despite Pocket NC specifically saying their V2 was designed to mill materials up to that hardness. Details on end mills and feeds and speeds are shown on video. For each change in milling parameters, changes are noted in green (increases) and red (decreases). 0:00 - Facing PEEK plastic 2:54 - Reducing PEEK plastic 5:26 - Facing Aluminum 6061 10:45 - Reducing Aluminum 6061 12:57 - Facing Steel 4140 14:02 - Facing Titanium G2 15:42 - Facing Stainless Steel 303
