I’ve been battling an issue for a few weeks now and I’m at the end of my wits! If anyone has experience or suggestions I’d love to hear. I’ve already contacted support by email.
I have a second and new Glowforge basic. I’m seeing the same issue that the OP in this thread observed:
- the kerfs are slanted
- slots or finger-joint boxes do not assemble properly
- a circle piece can’t spin in place (since it’s slanted on the edges instead of flat it only fits in one way)
Side side of a finger-joint box piece. The box does not join up when you cut 6 out like this and wants to twist.
In addition, I’ve observed that engraves are sometimes out of focus, engraved too lightly, and/or not as detailed as they should be.
I thought that the issue was due to the crumb tray not being flat. I drew out what I think is happening:
I’ve tried to level the machine and added pieces of scrap acrylic to the four corners. I tried so many different arrangements but I can’t seem to get it right. (In my previous set ups, just shimming one corner was enough.)
While checking things, I noticed that my crumb tray wasn’t flat and rocks when removed and placed on a flat surface. It doesn’t move when it’s inside the machine, though. Support is sending me a new crumb tray, but I’m unsure if this was causing the issue.
I’ve checked the “normal” things like cleaning the lenses/ensuring they’re seated properly, removing any debris between the bottom of the machine and the crumb tray, etc. but none seem to help. Any ideas while I wait for the new crumb tray? Is there a better tool for leveling than a bubble level/phone app? Or a surface that makes leveling the machine easier?
Another possibility is that everything is flat, and somehow the machine’s gantry is not?
