Not really a troubleshooting question but…
I have a nubm44 6w that I am replacing my previous 3watt with. Can I just drop in my nubm with the same amp setting and have it run at 3 watts with no issues? I had it running at 2 - 2.1 amps. (Just one of the cheap generic ebay drivers). Perhaps I will up the amps a little too
My 5amp driver has not arrived yet and I need my laser running like now for customer work for XMas.
