Question 1

Is karmyogi free?

Accepted Answer

Yes. karmyogi is completely free to use in your browser — there is nothing to buy, install or sign up for to start jogging, designing toolpaths and sending G-code.

Question 2

Is karmyogi a Candle alternative?

Accepted Answer

Yes. karmyogi is the modern, browser-based successor to the Qt Candle GRBL controller. It runs the same kind of jog/DRO control, G-code streaming and 3D toolpath visualization, plus a full CAD/CAM workbench, with nothing to install.

Question 3

Which browsers does karmyogi support?

Accepted Answer

karmyogi connects to your machine through the Web Serial API, which works in Chromium-based browsers: Chrome, Edge, Opera and Brave. Firefox and Safari do not support Web Serial. Everything that does not need hardware also works in the built-in mock device on any browser.

Question 4

Do I need to install software or drivers?

Accepted Answer

No. karmyogi is a static web app that runs entirely in the browser over USB Web Serial — no installer, no drivers, no local server and no cloud round-trip. Your design files never leave your machine. It can also be installed as an offline PWA.

Question 5

Which machines and firmware does karmyogi work with?

Accepted Answer

karmyogi targets 3-axis GRBL machines and adapts to compatible firmware including FluidNC, grblHAL and Marlin, with experimental support for Smoothieware, Masso G3 Touch and Ruida laser controllers.

Question 6

What can karmyogi make?

Accepted Answer

CNC carving and engraving, laser cutting, pen plotting, PCB isolation routing and drilling (Gerber + Excellon), auto-soldering, glue dispensing, pick-and-place, welding, screw fitting, drilling, spring coiling and 3D printing — all from one dockable workbench with a live 3D preview.
