Theodore Gray gets a 130W laser cutter:


Interesting that the tube seemed to have been package separately but he said no alignment was required.

Does anybody know if glass laser tubes are made precisely enough that you can swap them without any alignment change?


This is a fine post. Picture of the delivery of the laser on its side just barely fitting through the door is epic. It’s a big laser.

File formats: welcome to laser work!

His video of the engraving at the angle of a cross section is super interesting and sharp.

And the whole idea of a spring scale made out of acrylic using living hinges is very clever. Many applications for mechanisms like this.
