And no one but me is worried about the strain on the honeycomb? I must be being paranoid, but it just seems like the honeycomb wasn’t designed to withstand forces in that direction – it’s strong and level, but I would imagine if you jam something in there tightly enough, you’ll bend it out of true comparatively easily.
I’m probably wrong, I should just get over it.
Edit: I was wrong and am now over it. I use pins regularly.
hey there… with an expensive delicate toy like Glowforge, I can understand your concerns. i have owned a laser cutter/engraver for about 12 years and the honeycomb is far more delicate on my other unit,
then this monster… im assuming that the GF bed is made of steel and my other is made of far thinner aluminum (could never use magnets). I had originally made my hold downs by way of 3d printing and they were rounded. Those babies worked great but put far more strain on the pattern then these do. I intended to just make new ones for GF with the same design but found the pattern to be FAR more irregular on GF and thus, wanted something that had some spring to it… I also wanted to design something that the community could just make with the tool at hand. some might not have 3d printing capability.
While i can certainly not guarantee that these will not deform the bed (someone might make them too big or out of harder material) I can tell you that i have zero concern on this and also, intentionally made them “fusable” so that they will break apart, WAY before the steel deforms … if they feel too tight and you have to shove them in with more then slight pressure, scale them down a bit and get a sweet fit. your bed pattern might vary from mine… there is definitely variation in the pattern. if you have any ideas of other questions, feel free to private message me…
I have to say thank you again. I started working with non-proofgrade materials and some of the ply I’m using is curved. These babies hold it down tight and I could NOT use the GF with out them. I haven’t seen any noticeable effect on the crumb tray.
i actually adapted these for the honeycomb in the universal laser at work (had to make them slightly bigger). occasionally frustrated with the aluminum honeycomb it has because i can’t use magnets, so these helped with a cut i did with some warped BB last week.
Out of the box thinking is good.
If you have that warped board you want to use and the Actual Middle is going to be scrap, punch a fast hole in the middle and you can also hold it down there as well as the edges.
it’s funny, i have a very different perspective on using the laser cutter than my architect coworkers. they’re used to working with our main model shop who has a very strict process on how they do things. very useful there because they crank out a ridiculous volume of architectural models, but always a PITA if i want to work with them.
so here i come and just do random stuff, like i do at home. and i’m way happier working w/our own machine because i can just do what i want (within safety and reason). i’m just hoping our architects learn to step outside their own boxes and get a little creative with how they use it.
Assuming you downloaded the .ZIP file, you need to “expand” that/extract the files within. Windows will often allow you to view the contents without actually creating the files, so you will not see the .SVG file to upload - try right-clicking on the .ZIP and see if there are options to extract/expand, then you should have a new folder with the .SVG files inside.
