As with any training that you don’t immediately put to use, the learning dissipates.
Before going in to use Blue for the first time in three months since my class, I thought it prudent to review the wiki page. Regrettably, the key links to resources don’t work. None of the Manual links lead to anything and the Blue Laser Cutter Settings page is blank.
@NickE I discovered tonight that the settings on Blue were never filled in. I’m not a major user, so I don’t have much to add to the wiki. Best I can say is that cutting 1/8” Baltic birch works at 100% power and 2% speed. Etching worked at 100% power, 60% speed.
