Back to yellow light and focusing even with new print head

Hoping I don’t have a giant paperweight. I’m out of warranty. Only been using my machine a couple hours a month while I recover from some health stuff.

Help a girl out?

Current situation: last night I was cutting some small files, testing a new idea for some earrings. Everything was fine until I did a cut in the top right hand corner and then I got the yellow error light. Restarted things and entered focusing hell.

Said okay well let’s try again tomorrow. Now it’s just repeatedly giving me the yellow doom light. Temperature is not the problem.

Previously: some months ago I had a similar issue. Yellow light, focusing. Sometimes I could get it to work but especially when I worked in the top right hand of the bed it’d just give me the finger. GF told me there was something wrong with my print head and I’d need to replace it for $400 ish.

A very generous human gave me their brand new print head from an unused machine and I swapped it out. Wanted to see if that really was the problem before I shelled out money my health hasn’t been good enough to make recently. It worked. I was able to get through Christmas orders and all that good stuff.

So I’m guessing it’s not the print head itself.

Everything is clean. Wifi is strong.

What can I do?

I think I might also be hearing a clicking sound as it is focusing.

That would be normal. The lens gets shifted up and down within the head to focus.

That’s what I thought but I’m hyper aware of it now I think XD

Upside, just exited focus hell but we’ll see for how long. I’m very concerned this is going to keep happening. It just started working again on like the 40th restart.

Sometimes the GF just has issues connecting to wifi. I had mine do that a few weeks ago and I just left it and came back the next day and it was connected. Never had a problem with it after that. I don’t turn it off though… So that might be part of why I see it so infrequently. I only power cycle it when I know there’s an update that it needs to get (or I want it to get). The yellow button thing… GF will have to inspect your logs to see if they can identify any specific issues. They’ll want to know when the last time it happened was.

The yellow light can also happen if the white cable doesn’t have a solid connection to that head - with it off, check that connection carefully. A few clips have broken, but in some cases it’s just not clipped all the way in.

This ^^^

Could also be the contacts between the head and carriage plate need cleaning.

Also please don’t say “paperweight.” It’s getting so overused, makes me just want to skip to the next message instead of trying to help. :stuck_out_tongue_winking_eye:

Hi @feeby123, thank you for reaching out to us. I’m sorry to hear you’re having some trouble with your Glowforge.

I extracted the logs from your Glowforge to investigate the problem, and it seems like your unit is running into trouble during the calibration step in which the lens focuses inside the printer head (you may hear this when it’s happening - there’s an audible “ticking” sound as the lens moves up and down in the head). There are a few different reasons this error may be occurring. Could you please check a few things for me to help narrow it down?

  1. Check the printer head lens by following steps 1-5 from these instructions: Cleaning – Glowforge. If you see anything unusual such as damage to the lens or debris in the printer head, please take a photo of it and attach it to your reply
  2. If you are using magnets to secure material to the crumb tray of your Glowforge, please remove or reposition them and try again. Magnets placed close to the printer head may cause trouble during calibration
  3. Check the connection of the printer head to the white ribbon cable in the printer arm. Turn off your Glowforge, unplug the head, and plug it back in. Note whether the cable plugs back in securely, and whether you feel it “click” into place

Please let us know how it goes!

Forgive me the slow reply! Migraine day! I will check all of this tomorrow. Thank you!

Hi @feeby123 - thanks for the heads up, no rush!

Please let us know if you run into any issues with those steps.

Again sorry for the slow replies, I’m still in recovery mode after a lot of stuff. Appreciate the patience.

I’ve gone over everything and I’m not seeing anything suspect from the list. The only thing that might need a little extra love is my lens/camera. It looks pretty clear but once I get some more wipes I’m sure it’ll be due.

I was able to get some cutting done yesterday for a bit which was a relief.

I don’t know if it helps but the big error seems to trigger when I try to cut/engrave anything at the furthest upper right corner for sure. Everywhere else in the machine it’s a “maybe” sort of thing but that spot is a no no. Makes me scared of doing bigger more complex designs. :s

Hi @feeby123. Thanks for getting back after trying some prints. I’m happy to hear that you were able to complete some cuts.

I know you mentioned noticing trouble when you try cutting prints in the upper right corner of the print bed. To help us see if the error we noticed before is still occurring, as well as troubleshoot any of the issues with cuts across parts of the print bed, could you do the following?

Once all these things have been checked, please perform the following test print.

  • Print the Gift of Good Measure on Proofgrade material, using Proofgrade settings, and place the design in the part of the bed you noticed the trouble occurring most.

  • When the print finishes, leave the lid closed and wait until the fans stop and the picture updates.

Check the completed print:

  • If the Gift of Good Measure fails to cut through, take a photo of the front and back of the print and attach these photos to your reply.

Let us know how it goes and we’ll look forward to hearing back. Thank you!

Thank you. I cut out a small prototype earring thing just before I saw this message- so if it helps narrow things down, I attempted the gift of good measure at 5:59 pm EST according my stuff. It yellow lighted right away.

To clarify, cause I realize maybe I’m too vague- when I clicked print on the gift of good measure all the way up in that corner it didn’t even get to the point of cutting. I click “print” in the UI and it yellow lights. I don’t get a chance to click it on the machine.

Hello there,
Thank you for attempting to run the test print as requested, I’m sorry to see that your attempt was unsuccessful When I extracted your Printer’s logs, I noticed a specific failure type had occurred. That said, can you please do the following for me

  1. Turn off your Glowforge (this is important to avoid damage to your unit)
  2. Open the lid and, using both hands, gently move the laser arm to the center of the bed
  3. Gently move the head under the lid camera
  4. Turn your Glowforge back on

After the printer calibrates, then attempt an additional test print by doing the following.

  • Print the Gift of Good Measure 1 on Proofgrade material, using Proofgrade settings, and place the design in the part of the bed you noticed the trouble occurring most.
  • When the print finishes, leave the lid closed and wait until the fans stop and the picture updates.

Check the completed print:

  • If the Gift of Good Measure fails to cut through, take a photo of the front and back of the print and attach these photos to your reply.

Let us know how it goes and we’ll look forward to hearing back. Thank you!

Kind regards,

Went to go do this and for some reason the files aren’t loading on the UI dashboard right this moment and since I’ve been doing prototype earring cuts now and then I’m not sure which file the gift of good measure is… so I’m gonna wait a few hours and try again.

Uh oh! Thanks for sharing that photo @feeby123

Let’s see if a hard refresh on your browser fixes this issue. To do this:

  • On a Windows machine hold the control and press the F5 button, or click the refresh icon on your browser
  • On a Mac machine hold the command button and press R, or click the refresh button for your browser.

I hope that helps!

Oh I had refreshed it a number of times lol. :slight_smile: BUT, in case it helps, I was using Safari on my iPad. I know there’s an app but the browser always worked better for me. As of this time it’s loading just fine. I plan on getting back to the laser dungeon in an hour or so and I’ll run that test. Thank you for your patience.

Alrighty. Attempted it again. Did exactly as written. Included is a picture of the bed image and where the piece of proof grade draft board is located.

I clicked print (in the UI), the print head moved over there, then a moment later another shorter movement and then the yellow light came on and the error popped up on my screen.

No cutting/engraving happened. It doesn’t get that far for anything over in that area.

It’s 2:26 pm EST so whatever print was minutes prior to that in the logs is the one.
