ok…well I suppose in the practice of playing with this and attempting projects one has questions…here is my new one.
I upgraded my laser to a 15 watt blue led unit. It uses either ttl or analog to control the beam power. I have it set to analog and said nice little Arduino is indeed sending out nearly 5v when asked resulting in a full 15 watts of beam.
The problem I encountered is that by following the recommended procedures for LaserWeb and GRBL, what I get after vectoring some text from a .jpg is LOTS of tiny straight lines in G code. Regardless of using an M3 or M4 in GRBL. I end up with a duty cycle to the laser of less than 10%
I have set GRBL to laser mode via $32. There must be something I am overlooking because I see so many successful results here. Any suggestions?
