Curved surfaces are mentioned in the video, in relation to the curve on a MacBook. What are the capabilities for curved surfaces? How much difference in height/depth across an engravable surface can there be? How about severe curves, as in bottles or glasses for example?
BTW, I sold my vintage convertible to buy my Glowforge! 
Iām not sure how youāll get a bottle or glass in the Glowforge as Z axis clearance is a maximum of 1.5" with the floor removed. Iām sure it will do most of one side of a pen though.
The focusable depth is 0.5", so you can definitely do the top surface of a pen.
Weāre super flattered and are pretty sure you can make cooler stuff with your Glowforge than you can do with your convertible. 
Hah! I just sold my 74 MGB convertible to do the same thing!
Waitā¦ I specifically bought my Glowforge to engrave my vintage convertible, and now I find the Z axis clearance isnāt big enough? Iām shocked I tell yaā¦
Seriously thoā, being able to put a 2x4 through the Pro model on itās side (Z = 3 1ā2") would be a monster architectural hit. Just a suggestion.
Duly noted, Simon. (That sounds pretty awesome actually).
I do wish it would be possible to increase the pass through height on the pro. I was hoping for something that could possibly make this baseball bat,
, possible. That all said, Iām looking forward to possible stitch & glue kayak designs.How high is the Proās bay door? Also, how does the pro continue the cutting, does it sync cuts given the previous cutting having a known edge?
I was thinking about how the continuous feed work would go, as well. Using the camera to sync seems the most likely. Sure, it isnāt possible with the Glowforge, but would the bat simply burn a strip at a time and line everything up with a similar syncing technique?
@koos42 the passthrough is 3/8, but itās aligned with the tray to be optimized for 1/4" material.
Is the 1.5" Z clearance the official number? Iāve been looking around for that info and havenāt seen it anywhere else. I was wondering about engraving on something like a pint glass, for example, and wasnāt sure if the machine would be able to handle it.
Thank you!
While it seems that the Z clearance may not be enough for a pint glass or baseball bat, that doesnāt mean you canāt use the glowforge as an integral part of the creation process. The laser cutter should be able to cut a pretty good stencil from vinyl sticker for sand blasting or perhaps acid etching your drinkware.
@septimus39 - in my limited experience, laser etched glass is not terrific (other people may have better results). I have had much better luck laser-cutting stencils and then using that to etch the glass as stated by @koos42
koos42ā¦ Just a heads up that you never want to cut vinyl in a laser cutter. Vinyl sheeting is made with Polvinyl Chloride (PVC). The chloride changes to chlorine gas when heated, and Iām sure you donāt want Chlorine gas floating around your workspace.
Good point. Now I have even more incentive to sell my 61 porsche. 
No! Iām all for the Glowforge, but not āsell-the-Porscheā for it. Let alone a '61. (A 944, thatās a different matter)
I donāt think I could fit it in the Glowforge to engrave it anywayā¦
Is there another stenciling material people use instead of vinyl?
Mylar or any other polyester film should be able to accomplish what youāre trying to do. Canāt speak from experience though.
I definitely sold my Chevrolet Nova to buy a Glowforge. Out with the old toys, in with the new tools!
to make sure Iām reading this right - we can cut/engrave up to 1.5" as long as it is small enough to fit inside the machine (without tray)? the passthrough cannot be used for anything larger than 1/4? I envisioned myself engraving lines and numbers on long boards for growth charts but would want to use thicker than 1/4 for something like that
PS I would love to see photos and videos of the machine being used with longer materials.
