I have been having trouble with cutting through objects for quite some time. But I always resolved with going over a second pass.
Now I’m afraid my first pass isn’t even burning.
Starting at 3:00, it isn’t burning for the first half. And that second pass didn’t cut through.
I’ve cleaned the lense on the left side under the cover, I’ve cleaned the lense on the side of the laser plate, I’ve cleaned the 2 sensors on the bottom of the laser head. I’ve cleaned the mirror and the movable lense in the middle with the lense removal tool.
Also I noticed the gradient in the engrave, using a doubled amount of power for the engrave:
And did a double pass at a slower speed for cutting
I’ve got an external fan with filter, it is working well, haven’t used it since I tested it for about 20 minutes last year. I haven’t used this machine in over 6 months.
I’ve cleaned the trays, I’ve even checked and cleaned the laser plate by removing it using this video: How to Remove the Carriage Plate on Your Glowforge - YouTube
The lack of cutting only happens after an engrave, and it happens anywhere on the board. I’ve done this test 5 times from top left to bottom left. If I start with a cut, it will cut, every time.
Ideas? I don’t know what else to clean.
