Lightburn version for Xtool D1 Pro 20W?

I am sorry if this has been asked before, I have searched and searched but unable to determine which version of LIghtburn I should purchase for my Xtool D1 Pro 20W. New member and new to laser engraving, I would greatly appreciate help in knowing what version to purchase. Thank you very much

G-code is the minimum version that you would want. In fact, the DSP version would also work for your laser as it includes g-code functionality in case that’s something you also needed.

Thank you so very much for the information. I greatly appreciate the help.

So which one should one purchase for D1 pro 20W? Does my machine use DSP? GRBL? G Code?

This would be a g-code machine.
