Wasn’t really sure how to title this one but @dan_berry is this what you had in mind for a test?
A series of rectangles with white space between them, to test how quickly the laser switches on and off at maximum speed, full power, using both PG acrylic and PG maple ply.
The plywood sample has my trusty broken-tip X-acto in the frame for scale reference. I did not clean any of the char or soot from this one because I didnt want to break those super fine lines in there. That is impressive.
The red acrylic has one of those fine sewing pins in the frame for reference, I use this for applying CA glue to really small stuff.
