Last Week’s Goodies:
Highlights for the Week Ending February 18, 2017 Staff Smarts:
Does the Glowforge have 100% accurate cut-through capabilities on Proofgrade?
Editor’s note: something got lost in translation; this heading doesn’t match the question I thought I was answering. Proofgrade material will cut through every time (or it’s a bug that we need to fix). My reply dealt with the question of “can you precisely engrave to a certain depth.” You can engrave a 1/8" slot much more precisely in, for example, acrylic than it will be in walnut hardwood.
Sorry for any confusion - the answer here is “it depends on material”. We’ve taken the rather gothic approach of fabricating some of our Proofgrade material from the corpses of once-living plants, which leads to some predictable variations in the resulting product.
Or put another way, the depth accuracy will vary between materials like hardwood (poor) to acrylic (good).
Why is the laser tube mounted on the gantry?
@jamesdhatch - spot on.
Not measurably - @palmercr is right. As long as we don’t exceed certain parameters of force (which requires a bunch of specialized computation, but we do that too) the tube is fine.
Be a little careful about cutting exotic hardwoods.
One small note of caution: any time you use materials that aren’t designed for a laser, be careful. This board:
looks to my eye like lacewood, which is an irritant and might not be safe to use in your Glowforge.
How long will shipping to the UK take?
We don’t have transit times available yet I’m afraid.
Is the 10% shipping discount going to be extended?
I think we’ll be doing something here, but I’m not going to make any commitments until we get the bulk of our shipments in customers’ hands.
Pre-Release and Beta Pearls:
Man! That’s Sharp!
Since I was able to get some
practice in with creating 3d textures via deep etching I decided to try making something more practical with them. I had an old knife that I wanted to dress up a bit. First I took the existing side plates off of it so I could scan them into the PC with my scanner.
[image]I then took the scans into Illustrator and traced the outlines. I used a pair of calipers to measure the sizes of the different mounting holes and placed those over the scan in Illustrator as wel…
Gettin Jiggy With It!
(Dan insisted on that title
So, not sure if this belongs in Made on a Glowforge because it’s not a finished project, but I was looking for some community input.
I was in need of a 45 degree angle on some wood for some various projects (will follow up with posts on these eventually) and decided to make jigs to get me there.
This jig was relatively straight forward. I’m going to glue these guys together at the corners to form a 90 degree angle, so I didn’t ca…
iSense a Disturbance in the Force
Over the weekend I scored an new iPad Mini in trade for some IT work. I didn’t really check what model it was until I got home (Would have done it for free- but they insisted). Then I realized it was better (newer) than the iPad I already had. In which it had a iSense (a rebranded occipital structure) strapped to it. I temp connected the scanner to the newer iPad and immediately noticed the performance difference between the two.
When I got the iSense- I got with the the mount for the iPad I al…
Gettin’ It Ready to Engrave
This tutorial is long overdue, but I promised a few people I would post it, so here goes.
Im doing an engraving ive already done before so you can see some of the different options available when engraving something with a weird shape and an outlined cut. The outline part isnt necessary, but useful in a lot of situations, so this tutorial is a 2-fer.
This is the image we are starting with. Im going to be bringing it into photoshop to clean up, and get some of the initial shapes to move into ve…
Okay, Who Let Her In?
The Glowforge fairy left a deposit on my doorstep yesterday.
It’s a Pre-Release, so I have to give it back one day…but by all that is holy…they might have to physically remove me to get to it. (As in pry me off…crying. Or at least kicking up a hell of a fuss.)
I’m probably supposed to be all cool and adult about this…definitely not my style.
Those of you still hanging around waiting for this thing…
I actually had to wait until late last night until some…

It’s Knot What You Think
Had some leftover not too purple purple heart. Decided to see how a Celtic knot would come out:
So, Day Two, And This Happened
I needed a PDF to test, and didn’t have one worked up, so I grabbed one from our local expert… and the result is totally squeee worthy!
(For those of you who haven’t been hanging around, @smcgathyfay created this adorable Narwhal phone stand and shared it with everyone earlier last year…I’ve been planning to make one for myself ever since. You can too…I will post the link to her shared file at the end of the post.)
If you had any idea how excited I’m getting over this thing …
Girl with Gun (This is How it’s Done)
Fun in the Forum:
Hey folks–I recently watched a PBS special called
The Origami Revolution, about the use of origami in science and engineering. It’s a pretty cool show, highly recommended.
Anyway, early in the show was a demonstration by Robert Lang, noted origami expert, where he designed crease patterns on computer then used his laser engraver/cutter to engrave the patterns into his large sheet of folding paper. He was able to get extremely complex models this way.
This is a way old thread, but I saw this over the weekend and figured I’d post it.
It’s a tissue box cover made to look like a mid-century butterfly roofline house. You can’t tell from the pic, but the tissues come out of the chimney. My wife bought this to put in the vacation rental home that we own, which has this same roofline. I tried to convince her that I could DIY this once I get the GF, but she won. Although I’ll be trying anyways!
They also had a few other mid-century…
Sanding a Perfect Bevel
Free Online Vector Software
Here is a link to an online, free vector designer software package. Looks interesting and easy to use.
Laser Engraving Comparison on Various Woods
Someone posted this on the laser forums earlier today. It has some rare woods and show how they compare and take darkening from engraving.
sorry, long posting: executive summary = take a look at
http://www.levitada.com (read “About”, “How it Works”, “FAQ”)
details below describe http://www.levitada.com, a tool I made for us to use:
We want a way to swap Proofgrade materials once our “thanks for waiting” box of goodies arrives.
Some of us will want a lot of veneer but have no use for leather. Others of us will want a lot of leather but have no use for veneer.
How do we find each other? This forum is great …
I think this might be a tad to advanced and pie in the sky for the ‘project inspiration’ section.
Just a cool video I saw earlier, and look laser cut imo. Paper models that can fold and reconfigure into different shapes. Video sort of speaks for itself.
Trophies can be Inspiring
Anyone else have kinda weird things they geek-out on? I really admire nice trophies and just spent hours on Pintrest looking at them. (Good gosh, thought sounds kinda pathetic when you say it out loud lol :
) I think I like them becasue they are little sculptures with a specific purpose. I’ve had several requests for the sandblasted dog show trophies I’ve made, but just never had the time/energy to tackle orders. I think the GF might change that for me which is pretty cool.
Fractals Fractals Fractals…
This site has the free pattern for -while not really a jigsaw puzzle toy - but more of a “legoish” style toy. Interlocking pieces for creativity. Using corrugated cardboard looks like a simple but fun project.
Laser Tips for the Inexperienced
Alright friends, As
@Jules suggested, I am going to start a list of useful tips for the inexperienced.
Please add things that might be common knowledge to those who are comfortable with lasers but that might be big news to someone who is new.
We were crediting the folks who generated the tip; but discourse only allows you to mention ten members.
You want to go the fastest you can at the highest power possible to have clean edges.
