Voltage divider would be pretty slick to avoid the firmware update.
I can get a couple 100 packs of resistors for a few bucks to make it easy for people who want to try it.
My laser kit is on the way, and some safety specs!!!! Leo69 you are the man, you made this so easy for me. I don’t want to sell the diodes, DTR is doing a great job of that but maybe I’ll get a stack of the heat sinks and power supplies bundle them with the resistors for the makers that are impatient. Maybe some molex connectors and plugs to make this an easy swap with an extruder. Sorry, I’m just excited and I don’t want to have to wait for my power supply from china….
