[Shane] needed a UV exposure ... all the useful light out of the box. A pane of glass was cut to fit on top of the planter box, giving you a nice surface to place curing PCB’s on.

Instead, it uses a photosensitive resin that reacts to UV light, forming a solid and durable coating on the PCB. UV-curable solder mask can be applied by screen printing, spraying, or dipping ...

and a UV light source is used to expose it. Afterwards, isopropyl alcohol can be used to wash away the unexposed mask, leaving behind your PCB design. You’ll still need to chemically etch the ...

TLDR; This project hardware is based on Diyouware PCB-MKI and software is modified Marlin 1.1.9.1 ... It uses so called astigmatic method the built in photodiode array UV light and calculuates whether ...
