Oh, another thing to check is the airflow into the unit on the right side–make sure there’s nothing blocking that or a piece of paper stuck up on the underside–something else I’ve learned to check for frequently!
As others noted, you shouldn’t need to clean before every use, but when you do clean, make sure you get everything…
Also consider the ambient light–e.g. close to a window that gets lots of sunlight? Though most often that affects trying to center/focus, bright light may affect more–e.g. summer worse than winter months? I recall I had a “loss” of power after a while–I started using my unit in Nov 17, have it next to a south facing window–and seems it was spring when did notice “loss of power”–but now in the habit of closing the curtain if it’s not fully overcast day, and the laser power has been consistent… May be pure coincidence, but it eliminated a variable from the environment!
Hi @sarjanlong, I am so sorry you are having issues cutting through Proofgrade Material! Thank you for taking the time to do some initial troubleshooting. Can I have you check a few more things as well?
Please send photos of all your cleaned optical components, with special attention to any damage you might find:
The printer head window, on the left hand side of the printer head
The laser window on the inside left of the Glowforge
Thanks for checking on the details. Yes. I have cleaned all of those. This machine has never cut all the way through proofgrade. But the advice I always got was to reduce the speed by 10%. That was enough until recently. The last cuts I did were ridiculous. Even 2 passes at reduced speed didn’t make it through.
I see a message from support so I will follow their guidance now and see where that goes.
Is the lens inserted correctly? If it was doing okay until a recent cleaning the lens might have been inserted upside down. That will keep it from cutting through, and it happens a lot more than you’d think.
I did a cleaning of all the optics and then pulled the tray out and cleaned the bed and dimples. Then checked the exhaust fan which really didn’t have a lot of gunk in it. No obstructions to the air intake.
Then I put in a sheet of Medium Draftboard (full sheet held down with T-Pins) and ran the Gift of Good Measure print with everything set to default. The print did not come close to cutting through. Not even a hint of it. Time of print about 7pm EST on 9/5/2019.
What else do I need to provide? I also have a video of the cut in progress and the finished product. I can upload those to dropbox if you would like them.
