Can barometric pressure affect my Glowforge?

When I first got my GF I remember reading that certain types of weather conditions could affect the GF negatively, as in humidity and such. Well I live in south Louisiana and we have hurricane Ida coming, which is supposed to be a category 3 when it hits. Its now Friday, and it should hit Sunday night. Does anyone know if I should stop using my machine right now until the storm has passed because of the barometric pressure? I don’t know if this is a silly question or not, but I’d rather be safe than sorry. Thanks!

Pressure, no problem. Water and power outages, might be a big problem.


the ONLY thing that has had any effect on my GF has been humidity.

Yes, you are right about that! Thanks!

Thank you!!

Well, keep it away from Tornadoes too, okay? :joy_cat:

Although on a serious note, if you are having some serious lightning, it would be a good idea to turn it off and maybe unplug too. A power surge from a close strike can damage electronics.

You’re good. I’ve ran the Glowforge between sea level and 10,000’ or so and no effect on pressure.

Stay safe!


I’m in south Louisiana too! I’m in Thibodaux. Where are you?

Pressure only drops very near a hurricane, at which time that is the least problem :grimacing:

Beg pardon? I know quite a few meteorologists and atmospheric scientists that would disagree with this assessment. :wink: Roughly speaking, the wind always blows from an area of high pressure toward an area of low pressure. Hurricanes and tornadoes are the most extreme examples, of course.


Yes, which is why the power of a hurricane is often measured by the low pressure at the center.

In this case the purple

When you are “in” a hurricane, or just outside is perhaps a debate but below 1000 hPa does not arrive until very near the eye and not hundreds of miles away.

Ok - I see what you were driving at now. I would have agreed with your earlier post if it had said something like “Pressure only drops below 1000 hPa very near a hurricane.”


There is quite a gradient but inverse logarithmic or whatever but I thought that while my sentence was not a math formula it got across the idea that if you were days or hundreds of miles from a hurricane barometric pressure issues were not very relevant.
