Great writeup, Leo! Very clear and easy to understand. I’m guessing you’ve written instructions like that before.
One question – I noticed that you’re measuring amps in line with the laser when setting the amperage. On the JTP driver, they tell you to leave the laser disconnected and just measure amps across the output terminals. Are those two readings the same thing? Does that mean I could buy a digital ammeter and shunt and leave it hooked up all the time to get a real time amperage reading for the laser?
Thanks again! If I decide to supplement my JTP, I will probably go this route (with a different machine, since the controller needs a firmware change).
Is there a higher wattage option for this? Since the 3.8 watt JTP laser is $450 or so, this might be a good option if I want to step up the power later.
