Or not. I have been begging Santa for fiber laser for years and this year seems like I behaved myself good enough to deserve it. Crate weight was more than 60kg, pulled my back while carrying it but I don’t complain. Marking It’s quite opposite to 3D printers where material is being deposited. Laser energy […]
Read MoreStressing C1 camera
I know from previous experience that Kurokesu C1 camera can handle decent temperature range, but only today made proper tests in thermal chamber.

In volume production time is everything. Every second counts. That’s why industry has invented test jigs. My test fixture is dead simple but does what it is designed to do.
