I’m sorry for the ongoing trouble and frustration when trying to use Set Focus with a material that has worked well for you in the past. Did you happen to have a chance to take the photos I mentioned in a reply to the original thread you created for this issue?
I’m sorry to hear that the issue is occurring with more than one unit. We haven’t released a recent software update which would impact how material is measured.
I’d like to check the logs from your other unit as well. Unfortunately, when I look at the user account for the email address that you use to log into the forum, I only see one Glowforge that has been active recently. So that I can locate the logs for your 2nd unit from today, would you please send me the serial numbers for both of your units that is located on a label on the back of the machines?
You can email the serial numbers to our team at email@example.com and let them know that the email should be forwarded on to me.
Also, any photos you can share showing how your material is currently set up on the bed of your units would be very helpful as I investigate this issue further.
Once I have both your unit’s serial numbers along with photos of the material and how its set up, I’ll review everything carefully and then provide advice and next steps. While taking the photos, if you can also take a photo of the bottom of the print head I can take a look at that as well to check for anything unusual.
It’s possible that the material has a textured surface which could contribute to intermittent trouble with height measurement, and photos of the material and setup can help me to either verify or rule this out.
If you would prefer to share the photos privately, you can send them to my attention at firstname.lastname@example.org
