General 2D Toolpath instructions:

# Cutting Depths: Start Depth tells the computer at what depth you wish to begin a cut. Unless you have already removed material over the entire path of the cut, the start depth should be zero. Cut depth is how deep you wish to cut. For a through cut set the cut depth equal to the thickness of the material.

# Tool: Selecting your tool is important. For most operations a 1/4" end-mill will be sufficient. The biggest things to be aware of are the tool number and spindle speed. The tool number tells the computer which tool it is to pick up. The CNC is dumb and will not know what tool it is holding at any given time. All it knows is the tool number. it is ABSOLUTELY CRITICAL that you enter the correct tool number for all of your tools. Breaking off an end-mill spinning at 18000 rpm that shoots across the room impaling you and your beloved engineering classmates will not score brownie points with anyone. Also check that the rpm are appropriate, typically the default is fine.

# Passes: Adjust the number of passes such that the pass depth is less than the diameter of the end mill you are using.

# Ramp Plunge: This option plunges the end-mill on a ramp instead of going straight into the material. Generally it is wise to use this feature because it reduces the forces on the end-mill.
