  • All joints are machined fully flat. No special jig or fixtures are required and therefore board length is not limited by table height (clamped vertically).

  • Direct G-Code generation from specified joint dimensions. No CAD model or drawing required.

  • Almost any desirable board thickness is possible from <1/8" to >2" . This is limited only but the bit size, the machine working area and the accuracy limits of the setup

  • Both sides of the joint may have different thickness.

  • Job type can be defined as single ended joint half, matching joint ends adjacent or complete drawer/box side board with joint machined at both ends. A special mode is available to machine the complete set of boards to make a 6-sided cube or a 5-sided box with finger joints on all edges.

  • Optional grooves or rabbets on box/drawer top and bottom to insert bottom or top

  • No bit radius related gaps, dogbone fillets or crevices. The joint is practically void free.

  • The generated g-code will cut the joint features and cut off/square the board end as well as sides. Board end cutoff can be limited to "onion skin", resulting in tabs for the finger ends.

  • Variable finger width , length and radius. finger-free ends can be defined

  • Complex finger pattern can be defined with up to 19 different finger lengths

  • "Randomizer" button to create a random finger pattern for the selected bit size and material dimension.

  • Selectable over-cut (to make sure to cut through)

  • Options for half-blind joints, as well as protruding pins/tails/fingers

  • English, Spanish and German user interface


  • This software runs on Windows PC only. It is tested with WinXP, Win7 and Win10. Most likely it will also run on Win2000, Vista and Win8. Please use the Demo version to try out compatibility.

  • The machine control code generated is standard G-Code that should be compatible with most machines .

  • All G-Code is to be executed with a straight ballnose bit. Tapered bits are not suitable. For most joints a 1/8" ballnose works very well (and is cheap if something goes wrong). 1/4" diameter bits are also very usable, allow slightly faster cuts but require larger finger radius, i.e. not as much detail.

  • Important: the flute length MUST be equal or longer than the material thickness!

  • The board edge should be parallel to the table as good as possible.
