Laser firing but not burning

Hey there,

I have a Foxalien 20w diode laser that was working fine today until i swapped computers. Now the laser fires but does not burn/cut/engrave anything. I’ve tried lazergrbl as well and get the same results. Here is my gcode.

$$

$0=10

$1=25

$2=0

$3=0

$4=0

$5=0

$6=0

$10=3

$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=80.000

$101=80.000

$102=80.000

$110=3000.000

$111=3000.000

$112=3000.000

$120=400.000

$121=400.000

$122=400.000

$130=400.000

$131=400.000

$132=200.000

ok

If you still have access to the old computer, you should transfer all the LightBurn settings:

If it’s completely dead, then you must rebuild all those settings from scratch.

I have the old computer, but it has the same settings as far as I can tell.

What is the value of “S Value Max” in Edit->Device Settings? It needs to be set to 1000 if it’s not.

Also, are you using the units that you expect? Typically mm/min for diode lasers.

1000 for svalue max and in $30
mm/min for diode0

If you swap back to the other computer does performance revert to what you expect? If not, you likely have a hardware failure or other mechanical issue. Make sure that cables are all not damaged and well connected. Check lens for damage or residue and clean if required.
