Glowforge Laser head tear down for cleaning 

Somehow this got on my homepage. You're doing something right for the algorithm! (Used to be a laser cutter repair tech for FSLaser. This is a great video for this style of laser.)

Will this help with the lens moving up and down? Mine stoped moving and I don’t hear the click sounds when I turn my machine on.

Excellent training video! Very delicate assembly. One thing that may be of interest is wearing an ESD strap and grounding it to the GF frame while handling the circuit board. I have had issues in the past where a static charge damaged a board and you can't tell visually at all. Just an observation. Thank you very much, and also, do you know of any diagnostics for troubleshooting that are available? I would like to be able to check sensors and turn on fans and motors through an I/O service interface. I don't do Facebook, but I have been looking on GF community forums for info, especially for errors like "Head not found", it's like trying to diagnose your "Check Engine" on your cars. Thanks again!

Thank you so much for the videos! I have used several to help me. along the way with my Glowforge. One thing I cannot figure out is where is the temp sensor in the Glowforge pro? my pro is 3 months old and unable these days. Non stop temp error saying it needs to cool down. I have cleaned and cleaned everything, watched your videos and done everything. I dont know where this stupid sensor is to make sure it's clean. the support at Glowforge is horrible. I wish I knew that before buying, I wouldn't ever recommend these to anyone because of the horrible support. They just keep giving the run around. I live in MN and its literally -18 degrees and inside the house its 65 degrees. Thank you again!

How about measuring out that gasket so a new one can be cut on the GF before pulling the head open.

My laser isn't cutting all the way through (but it's close) even on proofgrade material. I've noticed the focusing beam happens twice now (and seems slower than the usual quick flash). My gut is that the inside of the focus lens needs a clean. Does that sound right to you?

Would having ash or a foggy lens on the print head cause an orange light? I’m not sure where to go now. I get an orange light on start up, the head moves forward and to right about an inch each way and then I get the orange light. I’ve replaced the white lid ribbon, the black lid ribbon, the white printer head ribbon, the carriage tray, and the daughter board. If I place the printer head directly under the camera it either gets stuck center or homing and sometimes gives the error “head not found” other times it just sit there.

Do they sell the rubber gasket? Do you know where I can get another one?

Hi, I ended up unscrewing the Cap and three lenses came out. How or in what order do I put them back in?

Hello, this video is super helpful. I followed your instructions but i used 91% isopropyl alcohol to clean the small fan blades and the board with a very soft brush. I put everything back together and when i am going to do a calibration I get the flashing yellow after I press the blue flashing button. The calibration cannot be started. I am stuck 😢. I checked everything again and putting back together. I double check the white printer cable and it is set properly. I also check the 4 pins and they are making a good connection. Did I messed up the board by using isopropyl alcohol to clean it? I mean it does not make sense. I let it dry out. I cannot use my machine now. 😢😢😢

I’ve been trying to find a laser tube replacement tutorial since that seems to be one of the parts that inevitably fails. The cost of shipping it from where I live to get it fix would cost more than getting a custom laser tube made here 😅 Just wanted to see if you’d ever do a tutorial

what did you use to clean the motherboard?

Hey man I really appreciate your videos, I am interested in buying a part I need. I’m from Washington state, If I have trouble I’d like to see if you may help. Thanks

What is the purpose of the window on the side of the laser head?

I took apart the screw cap part you didn't clean and now I dont know how to put it back together... do you have a video showing this?
