After stinking out the building with an open frame laser, I set up the enclosed Creality Falcon2 Pro 40W and use it to cut a hinged plywood box for a 48K Spectrum.
My old microscope ran out of room for bigger boards. I build and test the Tomlov TM4K-AF Flex, a 4K HDMI autofocus microscope on a flexible arm, on real PCBs.
