It is possible to make grooves with the Glowforge machine?
, or not is recommend.

Thank You

Not enough information for me to go on. What type of grove, in what material?

Do you have a photo or drawing of what you want?

If I understand your question -
I have used engraving to create a channel for a sliding top to a box. It only required enough testing to get the depth and clearanceI was after.

Yes, I do it all the time.

It takes some experimenting to get the grooves cut to the depth that you want. I’ll generally run a few small test engraves with Full Power, High speed and a fairly high LPI. Then I’ll increase the LPI to take it deeper. (Make your hole a little larger than needed, deep engraves tend to load up one side with resin. Or you can scrape it out after.)

it is possible. it’s not particularly efficient and, as @jules said, it requires experimentation to get the depth you want.

Like this?

I had a harder time keeping the ears to fit in the grooves and ended up with a piece of 1/16 BB plywood. Some work with a needle file was needed to get sizes just right at the end

It was in the title!

Yes, you can make a groove!

So I posted this some time ago. https://community.glowforge.com/t/can-i-make-a-groove/1436/ Now that I have a glowforge, I can make it myself. I generated the finger jointed box here… http://www.makercase.com/ Then went to Illustrator to remove the top row of fingers for the sides and al of them for the top. Then started adjusting the top and added the raster shapes for the grooves. [pencil_case] I used medium maple plywood and adjusted the engrave to make two passes to get th…

I am surprised the forum software didn’t suggest the post before you submitted your question.

Thanks Markevans for the help

The grove is about 9 inches long by 1/4 wide at a depth of 1/8

What power, speed and LPI could you use?

It depends on the material, there is no way to come up with a set of numbers that works in all cases.

But what I do when testing a new material is create a very small filled test square, about 1/2", then start with the HD engrave settings. They will probably not engrave as deeply as you want the first time, but with the next test, just increase the LPI. Try it again and see how that one does. If it gets halfway there, for the third test, use those settings and two passes. Just keep increasing the LPI and the number of passes until you get it deep enough.

Okay, I undersatnd now and @Jules has the answer above. Good luck with your project.

For every new material I make one of these…

Has anyone been cutting 0.37-0.40 material?

I made a few changes. But left in the GFUI you should have to set it up only once. the engraved circles should be twice the speed indicated for a full range and all at full power or other [power specific to the piece. [evans%20tests] edited for improved design

It can be used even if all there is, is a single 3x12 piece of wood, and it would not do to use up the whole piece of wood to know what the settings should be. That can inform me of the settings needed and how prone to burning that wood is.
