[bosondehiggs]

Hello i want to add a osram PLTB450B on my prusa i3.
i buy this driver :
12VDC Power Supply Driver for 405nm 445nm 450nm 520nm 200mW 3W Laser Diode w TTL | eBay
and received one 1W~2W...
but i dont know how configure it.
how setup voltage and current?

thanks

There is a "pot" that can be turned to change current. I'm pretty sure voltage will stay at 12V regardless of current.

Look just to the left of R2 , the first component on the left is the pot. I would suggest using a multimeter/ammeter to check the current while turning the pot. Can't determine output current safely otherwise...

Hope this helps

usually the adjustment is a phillips screw IIRC, could be wrong, only seen them in videos.
