Answering your question, the 170mA current was measured when connecting the laser directly to the 12V power source with a LM2576HV Step-Down Voltage Regulator which has a high current limit (see pic below). The measurement was done without Ramps board. I currently don’t have a cheap 5V power...

Right! the mistake cost me a lot haha. I wired the other diode using one of those voltage regulators to step-down the voltage to 5V and they both seemed to do the job:

Thanks for your reply! Great to hear the step-down converter is sufficient. However, I’m still confused regarding the current and power output. When I measured the current flowing through the laser, I got a 170mA reading. Am I in this case using the maximum power output of the laser (150mW...

Hey guys, I toasted an expensive laser by connecting it to a Ramps 1.4 board supplying 12V. Apparently, the laser is configured to work with 5V. I wanted to test whether it works and I had no idea it’s very sensitive and would take a fraction of a second to damage it beyond repair (I tested...
