The short answer
If you want a mature one-time purchase, LightBurn Pro drives EZCad2, EZCad3 and BSL boards from version 2.1. If you want free and do not mind a technical setup, MeerK40t drives EZCAD2 boards, and Balor is a command-line option for JCZ LMCV4 boards. If you want to run the galvo from a Mac, Windows or Linux and keep design, photo preparation and camera placement in one app, Vextrify drives JCZ/EZCAD2, EZCad3 and SEA-LASER/BSL boards. Find out which board is in your machine first: that decides everything else.
