Focus on 3/4” bamboo cutting board

[Jules]

Autofocus is not enabled yet AFAIK, and you can’t use anything thicker than about 0.5 inches on top of the crumb tray.

The laser needs a certain amount of distance to focus the lens … as you discovered.

If you want to engrave on something thicker than half an inch, you need to remove the crumb tray and prop the board up so that it falls into a certain range for the laser to be able to focus on it.

There’s a really good tutorial that @henryhbk did that shows how to do it here:

Tutorial: How to cut without the Crumb Tray (Honeycomb)

Tutorial: How to cut objects too thick to have the honeycomb in place The GlowForge has a maximum material thickness it can cut through, but there is a maximum thickness you can even put on the honeycomb (crumb tray) even if you are surface engraving as the laser has a limited focus range of 0.01" - 0.4" *** above the surface of the honeycomb at the time of this tutorial. But let’s say you wanted to engrave something thicker that fits quite nicely inside the GlowForge but not with the crumb tray…

Sounds like you got lucky with the distance on your second shot though, so that was a good thing.

Sorry about that.
