Fusion360 with hsm works was free for students and small business. Has a great verifying software that allows you to see what it is actually cutting. Highlights the already cut area and the newly cut area.
Takes a bit to learn though.
Kelly was also doing some software for cuemaking. I have his balance and design program, but have not yet got his Cue cutting yet. I still have not got a 4th axis. I use the hsm works on my router and like it very much. The downside is that it requires internet all the time to use it, as it is cloud based, that side I find annoying.
Do try and learn what the gcode does and how it works.
Becomes very useful for simple things , and with NOTEPAD or basic text editor, the code can be typed in a few lines, and the header stuff can be copy and paste , as long as it is the right format for your machine etc.
