LightBurn has separate licenses for GCode, DSP, and Galvo.   I have the GCode I use for the xTool P2 that I paid $60 for.  If I wanted to add DSP it's another $60.  Galvo is anther $90.  If you want any one license, the GCode is $60, DSP is $120 and Galvo is $150.

In other words, LightBurn is a great choice, but you might want to settle on a machine before you buy the software, so you don't pay for a license you don't use.

Also the xTool software is pretty powerful, and comes free with your laser.
