Hi, i’m trialling LightBurn, using a LaserTree F45 (10w optical power) on a stock 3018 CNC Pro).
My laser is burning very faintly, i’ve read the Common Grbl Setups and Configuring a 3018 CNC and also watched some videos.
I have laser mode on.
$30 matches in the software and the hardware at 1000.
$110 and $111 are both 2250 which is correct and tested for my steppers.
The laser burns with the same faintness through an entire power/speed greyscale test.
$0=10
$1=25
$2=0
$3=2
$4=0
$5=0
$6=0
$10=1
$11=0.010
$12=0.002
$13=0
$20=0
$21=0
$22=0
$23=0
$24=25.000
$25=500.000
$26=250
$27=1.000
$30=1000
$31=0
$32=1
$100=800.000
$101=800.000
$102=800.000
$110=2250.000
$111=2250.000
$112=500.000
$120=50.000
$121=50.000
$122=80.000
$130=300.000
$131=180.000
$132=45.000
It’s fixed focus at 45mm but i did the height positioning above the test material (birch plywood) by moving until the dot was at its smallest and it measures at 45mm.
I’m sure i must be missing something obvious but it’s a new laser to me, having only used my old K40 before, so i’m stuck for what to check next, any help greatly appreciated.
Thanks, Gary.
