Hi Everyone…my GF started to have a loud vibration right at the start of the fan firing up but then ceased within a few seconds…now it is constant. It is vibration my wood out of place as the GF runs…I have cleaned the fan with Q-tips and with a straw cleaner brush but it is still sooooo bad. And not to mention horribly loud…any ideas of how to get this to stop. I have the GF Pro.
Check your exhaust fan. Might be crud on it making it out of balance.
Yup, most likely your exhaust fan has crud on it. A lot of us have turned it off and use external fans instead, but if you want to keep using the internal the official cleaning instructions are here:
I have a method you can use to clean your fan.
First, you’ll need to obtain a can of 3M Novec Electronic Degreaser, which you can purchase from
Amazon or Digikey.
Go to this URL: https://app.glowforge.com/maintenance/fan
That page will walk you through the cleaning process. Brief summary:
Turn off and unplug your unit and move it outside. Make sure it’s in a location where it has power and Wi-Fi
Using the fan maintenance page, you’ll be able to turn the fan on
Following all manufac…
but if you can’t take it outside or get ahold of the cleaning spray there is also these (this is what I do):
Happily, the Glowforge crew has released an “easier to implement” cleaning regimen for the exhaust fan now…instructions for how to do it involve purchase of a special non-flammable degreasing spray cleanser and use of a special cleaning mode of the software…instructions here:
Written up below is the old way that I was doing it…it’s a fairly labor intensive alternative that has worked very well if you are willing to keep up with it as you go along and not let it get …
@inmind4u I am so sorry your Glowforge printer is having a loud vibration as the fan turns on. Could you send me a few photos of your exhaust system? Specifically, please include pictures of the following:
The exhaust fan from the inside of the unit. To capture this photo:
Turn your Glowforge off
Open the lid
Using both hands, gently pull the printer arm towards you as shown below:
Move your phone or camera inside the Glowforge on the left-hand side, past the metal rail, pointed away from you towards the exhaust hose, to capture a photo like the one below:
A photo of where your exhaust hose attaches to the Glowforge, where your exhaust hose exits the room, and the path your exhaust hose takes from your Glowforge to the exterior vent or Compact Filter
The exhaust connection on the back of your Glowforge, with the exhaust hose removed:
Any area where you see smoke escaping from your Glowforge while printing
Once I have your photos I will be able to review for the best next steps.
Thank you so much for your reply. I totally understand. Please let me know how it goes. Sincerely,
