advice for a gcode generator

Hello to everyone

I have been using a taig mill for a few years but always programing myself the GCode.

I would like to know a set of cad - cam programs I can use to generate the gcode.

I am looking for something simple to use.
what I do most are mechanic parts to make my own machines and tools.
The software must handle 3D shapes and at least tree axis to generate the gcode
if that can generate code for a 4 axis mill that would be the ideal.

if it is free linux based software will be the best option to me otherwise something cheap please.

thanks and any advice is welcomed

Can you recommend something besides Fusion360? My shop is in a rural area and only internet available is through cell or satellite... both are expensive and have data usage limits so the cloud thing with autodesk is not an option for me. also, their software won't allow installation on a separate drive and my main drive is small. Too bad as I've heard it's a good program.

Thanks! Have you tried lathe support in Cambam? looks like it's new and still beta according to their site.
