Gcodai handles the hard parts for you. You just say what kind of part you want.
Design → Toolpaths → Simulate → Export. A “Next step” button walks you through one step at a time, and you can search for any command (Ctrl+K). Thai interface also available.
Pick the material and the system calculates depth per pass, feed rate and spindle speed, and picks a bit with a long enough cutting length. It checks the job before export, with a “Fix it” button.
Choose once: GRBL, Mach3, NcStudio, DSP Richauto, Syntec/LNC, LinuxCNC, MASSO and many more. For unusual machines, you can customize the file format yourself.

Gcodai Studio is web-based CAM software for CNC routers. You design signs and parts, then create ready-to-cut G-code. It picks bits, depths and speeds automatically and simulates the cut in 3D before you cut for real. It opens straight in your browser, with nothing to install.
It exports G-code in 12 formats: GRBL, grblHAL/FluidNC, Mach3/Mach4, NcStudio (Weihong), Richauto A11 handheld DSP, CNC-ATC with automatic tool change (Syntec/LNC/Fanuc), LinuxCNC, UCCNC, MASSO, Centroid Acorn, standard ISO G-code and GRBL laser. If your machine is not on the list, you can customize the file format yourself. GRBL machines can be controlled over USB directly from the program.
Gcodai Studio does the design and G-code generation (CAM) for Mach3 and NcStudio machines, but you still control the machine with its original software, because the controller is tied to that brand's card. For GRBL machines, Gcodai can control the machine over USB in place of UGS or Candle.
No install needed. Open gcodai.com/app in Chrome or Edge on a computer and start right away. You can also design and simulate on a tablet or phone.
Import SVG, DXF, EPS, AI, PDF, PNG/JPG images (convert to vectors, reliefs or halftone dots), STL models, and open existing G-code files to view the simulation. Line colors in the file set the machining jobs automatically.
Yes. Type Thai text with the 8 built-in fonts or add your shop's own fonts (TTF/OTF). Vowels and tone marks sit in the right place. Choose V-carve and the system picks the V-bit and calculates the depth from the stroke width. There is also a flat-bottom option that clears the floor with a flat end mill for wide letters.
The system calculates depth per pass and speeds from the material and bit size, picks a bit with a long enough cutting length for the depth, checks the job before export with fix-it buttons (for example deeper than the sheet, or bit wider than the groove), and lets you check the 3D simulation before cutting for real.
Yes. Use 3D → 3D slat wall, import an STL file, and enter the wall size, wood thickness and slat spacing. The system slices real cross-sections into slats, creates interlocking comb rails for the wall, engraves assembly numbers, nests the parts on sheets and exports G-code.
Yes. In Signs → LED layout in letters, choose an LED model and the system places modules in the letters, counts them, totals the watts and suggests the power supply and wire size. In Signs → Edge roll, it creates the return strips with V-fold grooves, joints and face panels, nested on sheets ready to cut.
