Thank you for reaching out to us. I’m sorry your Glowforge is having trouble calibrating. As @geek2nurse mentioned, the printer head lens moving up and down inside the printer head is completely normal, that is how it focuses.
I’ve extracted the logs from your Glowforge and looked at the trouble you’ve been experiencing. The issues you’re seeing look to be caused by a poor connection with the cables on your lid.
If you have not already done so, please follow the steps below to check the lid connections:
Turn off your unit.
Open the lid.
Using both hands, gently roll the laser arm to the front of the unit.
There are 5 clips pictured below. Check each one to ensure it is closed. The clip should lie flat, and you shouldn’t be able to flip it in any direction.
- If any of the clips are open, please take a photo and attach it to your reply. Don’t try to adjust or reseat the cable until reaching back out to us.
If everything is connected properly, it’s likely that the black cable on the lid has a problem and needs to be replaced. I can send you a replacement for that cable, along with some instructions on how to replace it so we can get you back to printing as quickly as possible.
Since we’ll need to confirm personal information to get the cable shipped to you, I’m going to send you a separate email with details. You should receive my email in a few minutes, but if you don’t receive it in the next 30 minutes please check your spam / junk mail folder. Once I know you’ve received my email, I’ll close this thread.
