I just got this email from FoxAlien, and thought others may like to see it…
After our intensive testing, here are some information about 40W laser:
Reizer machine or Reizer mega machines can support 40W laser directly.
If you use 3018-SE V2, LE4040, Masuter or 4040XE machine, please notice that when setting 100% power, the laser will power off to protect the motherboard. We recommend set 70%-80% power to engrave temporarily. Our team is urgently discussing the upgraded plan now. We’ll inform you at the first time.
