Laser on but not burning anything

Hi everyone,

I just setup my Laser Master 20W and it did a couple o 30 seconds nice cuts/burns and stopped working (with same settings and paper).

I have a blue led working and a weak red one aswell on top of the laser.

I am using a Mac and Lightburn. The machine is connected directly to the Mac with USB.

Here is a photo of my settings, 2 vidéos of the cut with the material at different heights and 2 videos running the “OrturPowerTest.lbrn” file I found on this forum:

Here are my machine settings:

$0=20 $1=50 $2=0 $3=1 $4=0 $5=0 $6=0 $10=1 $11=0.050 $12=0.002 $13=0 $20=1 $21=1 $22=1 $23=7 $24=600.000 $25=3000.000 $26=100 $27=2.000 $30=1000 $31=0 $32=1 $33=250.000 $100=80.000 $101=80.000 $102=80.000 $110=9000.000 $111=9000.000 $112=9000.000 $120=2200.000 $121=1800.000 $122=2500.000 $130=160.000 $131=150.000 $132=1.000 I don’t know what I did wrong and can’t find any help online. Thank you for your help! Sébastien
