[title] The Sacrificial Board
[* black] Milling will often require that you use a '''sacrificial board''' under your material. You will secure the sacrificial board to the milling platform. To get started, we have provided you with a sacrificial board, as shown in the ''second image''
[* red] The sacrificial board allows you to cut entirely through the material you are milling without cutting into the metal milling platform
[* icon_reminder] If you are engraving material or not cutting through your material you will not need a sacrificial board. If you are cutting through your milling material you will need a sacrificial board
[* red] The ''second image'' shows an example of a part that was entirely cut out of the milling material and the mark it left underneath of that milled part on sacrificial board. This is an acceptable and common practice for milling operations
[* icon_note] You can mill a flat recessed pocket into a sacrificial board to create a perfectly flat and level mounting surface for very high accuracy operations. Use this technique for milling and drilling PCBs, very thin material, or highly detailed engravings
[* icon_reminder] The sacrificial board can be wood, MDF, plastic or firm foam. You will not have an issue with your sacrificial board being cut and slowing down your cutting speed
