Visualize tray height for irregular objects

So, take your laser level (you have one, right?)… raise it to the exact height you want to test, i wanted to see exactly where bed height would be in on a skull I plan to engrave.

Now I just need to devise a very precise tiny scissor lift to raise and lower the laser to arbitrary heights, and I can use it to determine real heights of lots of items.

I think there’s some real applications here, and while there are probably more accurate ways to visualize this, I liked the simplicity and direct nature of this method. I’m sure clever forum people will come up with ways to improve this, that’s the beauty of the forum!

Since I used cutoffs as spacers to raise my laser to the correct height, this is almost “made on a Glowforge”, right? :wink:


Check it out! :sunglasses::+1:

Bigger than you want and kinda pricey, but they do exist.

I can only describe that price as ‘awe inspiring’ !

If you’ve got a glowforge - build one.


That’s cool but yeah expensive. I was thinking more like a milling table.|THD|google|&mid=sb5qX5Nwc|dm_mtid_8903tb925190_pcrid_195274179091_pkw__pmt__product_203459566_slid_&gclid=CjwKCAiA-9rTBRBNEiwAt0Znwy8FPml9D1QQUarFO4RjC_UtDXwmnDjLVfOttx7XG35XyIajUWQ3kxoCp8cQAvD_BwE

Oh yeah, much better. Now motorize it. :laughing:

If you have a 3D printer, this scissors jack prints in a single job, ready for use. I made one a couple of years ago and gave it to a friend…


I had that one in my collection to print. :grinning:
(Then this nascent laser thing came along, and I got distracted. Never did run that one.)
