I should have read the forums better but I purchased a K40 that came with a digital percentage-based power control. That is, you set the power for the laser from 0 to 100%. The laser doesn't lase below 9% and I've been scared to turn it up much past this. So far I'm only cutting cardboard. I have two questions.
1. Does anyone have a similar setup and mapped percentages to actual power. (I wouldn't assume it's the same as mine but it's a start.)
2. I'm guessing an analog 30ma ammeter from amazon(https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1) would not be suitable. I suspect the high voltages demand something a bit more specialized. I have the "Green" power supply version (with the Phoenix terminal block). Does anyone have a recommendation for a suitable ammeter? Are these hooked up inline with the tube or some special output from the power supply?
Thanks,
