While ‘Dither vs Gray scale’ sounds like a movie, it’s the question K40 laser engravers ask themselves every day. I recently got a question on FaceBook asking me what the difference is between dither and pwm (he meant ‘gray scale’) engraving. In a nutshell: The pulse width modulation (pwm) signal used for gray scale engraving […]
This blog is about the Mini Gerbil acrylic case. You asked for it, so here it is ! You can use and modify to meet your own needs. Assembly Instructions The design is simple and just a slot and click mechanism for the case. The PCB is held in place by 4 stand offs (M3 […]
