What is GlowForge’s Stance on the use of magnets for work-holding inside a glowforge? If it is acceptable then are there any parameters (size, strength. etc…) to keep in mind? If this is not acceptable or not recommended, are there other ideas for work-holding thin and flimsy material? I know a l…

My recollection is Glowforge made a big deal about the honeycomb tray being ferrous specifically for that purpose.

I did a forum search, but I did not find anything. I think I remember something like that as well, but maybe I read it in a thread that was not directly related to the topic? Maybe I just did not look hard enough. However, I figured having a forum thread that is hopefully easy to find would be good …

A search on “ferrous” turns up several hits including one from @dan confirming that they went out of their way to use a ferrous tray (including the one @markwal just posted as I was typing this.

As far as restrictions height is the only one I can think of. Keep it under a 1/2" from the tray.

I’ve been frequently using rare earth magnets to hold down the lighter materials and to address slight warping in materials – they work really well.

@karaelena made a hilarious video post that showed the head sweeping over the work and sucking the magnets off of the bed. “Now you see 'em , now you dont.” :rofl: So strong magnets are good, stronger than the ones securing the head.

Would something like this work pretty well? https://www.amazon.com/Neodymium-Magnets-N52-Super-Strong/dp/B01LYU3SX8/ref=zg_bs_1265130011_18?_encoding=UTF8&psc=1&refRID=KFA9WZXDT6TW6FB38VJS

Just remember to wrap a tape strip on them with an inch or so overhang for a handle. Can also mark them on one side so know how they go back together, and avoid a finger nip when they get close together and squirm out of your grip. Some of them are strong. Really strong. If you have an old hard dr…

Will be the tray magnetic? Community Support

Unfortunately ferrous metal grates are a lot more expensive than aluminum, even though they last a lot longer. Fortunately we love you all and sprang for them anyway! Barring any manufacturing challenges (the comolded plastic/metal crumb tray is one of the most complex parts. after the case) magnets will work and the thing will be tough as nails. Literally.
