@Alex_Krause I’m still not getting a laser on/off via software, either by manually sending M3 S.XX or when I run g-code. I’ve uncommented out the lines you highlighted, and I soldered up another level shifter just in case the one I had was bad, and it’s still not firing.
G0 is laser off G1 is laser on
G1 isn’t giving working (when input into the code box on the main screen.)
@K1111 Using the L pin might require you to have a Potentiometer installed… right now without one I believe you are set at zero power… do you have any resistors laying around?
!@Alex_Krause I do!
Would it make sense to wire to the High pin?
I noticed some interesting behavior tonight. My meter kept jumping, and the pot would inconsistently adjust the current. I zeroed out my Smoothie by mistake, and so I hit the reset button on my X5, and I noticed the meter jumped by 5mA when I did! I tried it twice and that happened. Is this electrical interference or something else?
