    To set kerf compensation you basically cut a line and measure the kerf width.

    You do this for each material / consumable combination you use.

    In sheetcam you create a jet tool for each material / consumable / speed combination you use and enter the kerf width in the tool settings

    kerf_tool.

    Here is a DXF file and explanation on how to set kerf compensation in sheetcam - the file is just a line from (0,0) to (0,2)

    basically import the file, create a new jet cutting operation, select the tool that corresponds with the material and consumables you are using, cut the file, measure the kerf, and update the tool kerf width setting

    kerf_set.

    to fine tune kerf compensation very precisely you can cut this interlocking comb shape and adjust kerf compensation to where the male and female parts are exactly the same width

    you must flip one of the combs over and compare the fit at the face of the material - the edge and back of the material has a taper - do not include or consider the taper
