How is GCode Online different from regular CNC software?

GCode Online runs in your browser with nothing to install. It's ideal for generating basic G-code and for jobs where you want a quick preview.

Which file types are supported?

SVG, DXF and EPS for vector work. You can also create jobs directly from part dimensions.

What should I check before cutting for real?

Always check work zero, safe Z, material thickness, the bit, feed rate, spindle speed and your clamps, and run an air cut or simulation first.
