I havesome trouble today with engraving with a basic unit.
Yesterday, I did an engraving that stopped after 1 minute (instead of 30 min). No error message on interface, no couloured glowing button. Button stays white and fans were still running. Just the head doesnt move anymore. I have stopped everything turned off and do again. The engraving werefine this time.
Today, I have made several engraving without problems but my last one and the same issue. Engraving stopped after few minutes. I have tryed to do ascoring with the same file to check that it was not a problem on mydesign and it works great.
But this time I have tried 2 times to do the engraving again. And this time no miracles.It stops.
Anyideas? I am a little concerned when I see similar cases in the forum with asking to change unit. As I am a initial backer, warranty is over and I don’t think there are possibilities to repair it in Europe.
Pick up the printer head and wire ribbon. Make sure the tab on the wire ribbon is facing up. Slide the ribbon back into the head until it clicks.
As shown, lower the printer head over the metal plate so that it rests next to the two round posts. Then push it gently away from you – you’ll feel a “click” as magnets pull the printer head until it sits snugly atop the metal plate.
Thanks for the detailed support. Here are the photos enclosed. I have seen nothing weird. After repplugging the wire, I have tried to sart again the engraving. There has been no trouble. So maybe the wire has moved and provoked a bad contact?
Hi @marc.simon1. Thanks for getting back to us as checking those connections and sending us the photos. I extracted the log files from your Glowforge to help me review everything, and wanted to confirm that you are able to print and engrave after reseating the connections. I wasn’t able to see any noticeable damage or issues with the pins, and cable connections in your photos.
If you’d like, or if you’re still running into trouble, go ahead and try our test print by following the steps bellow:
OK so Ihave done the test with gift of good measure in metrics on proofgrade acrylic.
The engraving is perfect. But it has not cutted totally through the acrylic sheet but not far. A hard push with fingers has broken the small thickness of non cutted acrylic on the global object but I didn’t succeed on little holes in the object.
Hi @marc.simon1 Thanks for getting back with the Gift of Good Measure print. I’m happy to see engraving is working as expected, however see that you’re running into some issues with your Glowforge not cutting through the material completely. I can continue troubleshooting everything until we get you back up and printing without trouble. To help me address the issue of the Gift of Good Measure not cutting through, I’d like to get a better inspection of some optical components from your unit. Can you take photos of the following?
The printer head window, on the left hand side of the printer head
The laser window on the inside left of the Glowforge
Please find (at the end of the message) photos of optical components taken after cleaning with Zeiss Wipes for non cutting through issue. After that, I’ve continued engraving.
Test of “gift of good measure” on non proofgrade material : OK.
Project of long engraving on the same non proofgrade material: it stopped just before the end When I say that engraving has stopped, I mean that the head didn’t move anymore physicaly but on the computer interface, no sign of problem. The countdown continue as if all is OK and at the end says that the engraving is finished without trouble.
second try with the same non proofgrade material (engraving with a little different line per inch data) : OK
The second side of the project with another long engraving : it stopped at the very beginning
checking of wire : nothing seems wrong
another try of the same engraving : it stopped at the very beggining like the first one
another try of the same engraving with the little different line per inch data used before : it stopped at the very beggining. I was just in front of the glowforge when it stopped. The engraving starts normally and stopped at the end of a line. I have heard a sound (mechanical blocking??). After resume the print and open Glowforge, I don’t feel any mechanical blocking when I move the head or the arm.
When I move the arm or head slowly, it moves well. But if I move faster, some mechanical sound appear and I fell a sort of little resistance. It is not always at the same spot but kind of randomly. Here is a video with sound:
Visually, the belt seems to be ingood shape, without missing teeth. The sound reminds me more a problem on a stepper motor I’ve had with a 3D printer but without certitude.
I’ve made further tests with different speed and power of engraving. I don’t know if it is significant or just a coincidence but it seems that at highest power and highest speed, stopping is almost systematic and at highest speed but a lower power, problems doesn’t appear.
I finish with a new “gift of good measure” on proofgrade acrylic : result OK. No problem.
=> So the major problem is the random stops during engraving. On most engraving, I use the same parameters and since now no problems. So I don’t know how to understand the results by those tests.
Thank you so much for taking the time to work through the instructions my colleague Brandon provided. I’ve extracted the log files from your unit, and compared it with the additional information you’ve provided.
Unfortunately, it looks like your unit is experiencing an issue that we can’t resolve remotely. I want you to have a reliable unit, so I’ll be in touch via email to sort out the details. I’m so sorry about the bad news.
