I’m having another issue with the GF where the laser does not focus properly even with proof grade materials. See attached cuts, they do not go through and are very wide. We cleaned the lenses per the maintenance manual 3 or 4 cuts ago.
Any ideas? See attached print on medium maple ply. We had this occur last week on acrylic (both proofgrade and not) and after submitting a ticket to GF, it started working a couple days later, with no change on our end at all, but I got no explanation. Is there any troubleshooting we can do? I searched the forum and looks like some others are having this problem as well. Ps I did try these things: https://glowforge.com/support/topic/troubleshooting/cut-didnt-go-through-material
Hang tight for support. I had the same issues a few weeks ago and they did several software pushes to my machine to clear it up. My GF works great now, even better than before.
As @rpegg suggests, wide lines like that point to a focus issue. Do check to verify that the focus height in your cut operations is the same as the default listed for the maple ply, if that is the material you are using.
I think it was 3, may have only been 2. Right at the time I was feeling better and ready to start playing again the GF team had it figured out, and I’ve been very pleased since.
The only missed cut I’ve had since was because I screwed up the pew setting and ran it at 1. That doesn’t even cut paper
Update: Ok so the issue seems to have resolved itself. I fired it up this morning without doing any other cleaning and it cut through medium draftboard just fine so tried the ply once more. It did not recognize the QR code on the ply, but cut pretty good anyway–still more charred than the draftboard.
No idea how to actually fix this. So if support is still listening, please do give us any tips! It may be one of things that have so many variables, it’s impossible to pinpoint. But if there are known issues, please let us know. You can understand how frustrating it is when you’re depending on the machine…
As you said, there are many variables that affect cut-through. If you have trouble again with a print on Proofgrade material, please let us know the time and date so that we can research more fully.
Regarding the QR code not being recognized, I dug into the logs and it looks like there was a very bright light shining into your Glowforge. Would you try reducing the direct light overhead and see if that helps?
I’m going to close this for now – please post a new thread if either issue recurs or if you have another question.
