Karv’s 3D preview of a microphone design cut into plywood

The bit and cut settings used for this toolpath

Play through the toolpaths and inspect the simulated cut in 3D.

Microphone geometry on Karv’s design canvas — **Design the idea** Draw on the canvas or bring in SVG or DXF geometry.

A contour toolpath around the microphone design — **Plan the cuts** Choose how each shape will cut and organize the operations.

Karv’s machine workspace with jog, work-zero and job controls — **Send to machine** Carry your cut plan into an ordered GRBL job queue.

Your project stays with you.

Follow one project from the first drawing to the machine workspace, with your design, stock, and toolpaths together.

Send the job. Keep the order.

Group toolpaths automatically by bit, or arrange groups around layers and shapes for separate pieces of stock. Karv turns each enabled group into a job in an ordered GRBL queue.

Change the design. Keep your place.

Refine a curve or enter an exact dimension. Move objects between layers while preparing toolpaths. Resize the stock or switch between inches and millimeters with your objects still selected.

Settings for the setup in front of you.

Choose your bit, material, and machine. Karv calculates starting cut settings and shows how it arrived at them. Make your own adjustments, then save a recipe to use again.

Illustration of rough, finish and detail passes using progressively finer toolpaths

Give the project another dimension.

Bring in an STL or build a relief from your vectors. Position it against the stock, inspect a cross-section, and arrange rough, finish, and detail passes with the cutters you want to use.

Bring your agent into the project.

Connect an external agent through Karv’s command-line or MCP tools. Have it create or revise a design, organize layers and toolpaths, and save the project for you to review in Karv.

Will it fit your setup?

Karv runs locally on your computer. Use the built-in GRBL sender, or export G-code with one of Karv’s controller profiles. Open an existing .c2d design or bring in SVG and DXF geometry.
