I have one EZCad2 artwork file that will not engrave with any power. Has worked fine in the past. Checked all the hatch and pen settings and verified they are the same as all my other files. Even copied the logo artwork into another EZCad2 file that is working, deleted the hatch and recreated the hatch in the new file and it still engraves with very low power – only on that logo. Other artwork in the same file – hatched with the same settings – engraved fine with normal power. I am at a loss? Any ideas?
December 11, 2025What size circuit breaker do you guys use for a 100W MOPA fiber laser?
December 12, 2025Are you running multiple fiber lasers on a breaker? What size breaker are you using?
I have 3 on a 15amp 120v breaker. They don’t really pull many amps at all. I have a fan ,computer and belt sander on the breaker too.
For ventilation, I recommend checking out the Best Exhaust Fan for 60W MOPA Fiber Laser: AC Infinity Guide to ensure proper airflow while running multiple systems.
Additionally, it’s important to follow safety and ventilation protocols when running lasers at home. See our detailed guide: Fiber Laser Engraving Safety & Ventilation Tips for Home Users in 2026.
