I already looked before posting. Pencil icon missingā¦
So I went back after your reply. Why on earth would they make it different!!!???
smhā¦
Thatās possible, but I had removed the head from the plate several times before, as well as checked the white ribbon connector a couple of times. It wasnāt until I moved the focus ring that it started working again.
Anythingās possible.
Referencing the note from @Jules about the gorilla tape behind the black cable at the hinge, and not opening the lid all the way: This one time, I bought a great heavy duty preschool height table the perfect dimensions for the machineās footprint. And then I was thinking that it would perfect height when the machine was lifted by the old design of the air filter, but meanwhile I have been opening the lid wide and bending low to do the weeding.
Hurting both the back and the cable. Who knew. 
Since this is turning into a known issue, does anyone have any thoughts regarding it being outside the warranty? I know it doesnāt break the bank, but itās irksome.

The replacement cables that they are using now are an inch or so longer where it counts, so itās generally a one time fix if you are reasonably careful when you replace it. (Some people arenāt careful. READ the instructions they give you closely before installing the cable. Turn it off. Follow the directions.)
The cable costs something like $20 or so out of warranty. Definitely not a biggie. 
In a lot of cases they donāt failā¦Iām still on my first cable after a couple of years. It just depends on how people use it. (But you should probably get a taller table to save your back.)

Follow up, since my post a week ago, a new cable found its way to me in Big Bend National Park, I was able to extend the legs on my table, and I am back in business. For anyone that suspects the need for the cable replacement, it was a smooth process. (And agree with Jules to make sure you read, re-read, the directions. I hate thinking that I am going to mess up my investment. Just breathe: Youāve got this!)
I promise to not open the lid so wide moving forward, and glad to have extra length on the cable arm, just in case. And excited to save my back, too!

Thatās even better! Back in bizness! Happy cutting!

Thank you Jules for putting all of this great troubleshooting tips in one place!
Iām having the same issue, and followed every tip and trick in this (and other) forums. Then I got the point about the head not moving at all, and how we should separate that from normal issues. Thatās what Iām having, the head wonāt move at all, no matter where I move the head before startup. Is there a separate forum or list of tricks with the arm/head wonāt move at all on itās own?
Thanks in advance! (Yes, Iāve emailed support, but Iām trying to get up and running ASAP!)

No, although that can commonly be caused by a broken lid cable, we have to eliminate everything else first. If you have run through all of these tests, be sure to reply to your original email auto-response and ātell support specifically what you have checkedā so they donāt ask you to check it again. Saying you checked everything doesnāt tell them enoughā¦you might not have seen something. That will delay you further. They will look at your logs once they know you have eliminated all the other possibilities and possibly set you up with a replacement cable.

Great, thanks! Iāll do that now.
Thank you @Jules! My GF stopped 3 cuts lines short of finishing a batch of earsavers, and orange buttoned me. Thought it was just hot, so I waited a bit, but it never started back up. Tried the usual, off, logout, move to center, etc, stuck on focusing, no movementā¦ did that twice, came and found this thread linked on someone elseās support thread, and it was the cable on the laser head that had come loose!
Gave me a scare, but thanks to this guide I was able to get it up and finish those last few cuts. Yay!

My machine is stuck on centering.
WiFi is good.
Camera clean.
I donāt know what else to do 
Spent so much money on this machine and itās not working the way itās supposed to. I am so disappointed right now.
You need to post over in Problems & Support if you want to open a support ticket. Or you can email support ā but donāt do both, as it creates duplicates.
Have you followed all the instructions in the first post up above? You can have super good wifi and still have connection problems with the Glowforgeāthey can be pretty picky.
Thank you for the advice! I did email support and am waiting for a response. My WiFi is good and the machine was working fine last week so Iām not sure why itās stuck on centering now. Every time thereās an issue with it working as it should I feel like Iāve wasted so much money.

A lot of things can affect wifi ā another device using the same channel, for instance ā even something at your neighborās house. Or you might have rearranged furniture and put something in a place thatās blocking the signal from the router just enough to make it not work. I remember one person had hung a sheet of metal to hang their magnets on, and it was enough to block the wifi signal.
It could be a bad cable, or too much light shining into the machine, or reflective materialā¦but MOST of the time, itās the wifi.
I tried to put the router right next to the machine and itās still not working. 
There still could be another device interfering with it. Did you try changing the channel?
Some people have had good luck setting up their guest wifi account as 2.4MHz and using it exclusively for the Glowforge.

Unfortunately, I cannot use WiFi just for the glowforge as my son home schools.
have you figured anything out yet? Iām having the same issue, the last 3 weeks its been ātoo Coldā no its stick homing and centering and focusing
Support said that itās the cable from the lid?
So I had to pay for a new one even though itās not MY fault. Itās a defect in the laser?
