Hi, I have been using Lightburn since 2021.
Fantastic program!!! I updated the version from LightBurn 1.2.00, to the current LightBurn 1.5.06.
Now the laser goes to full power when it is at 10%.
I can’t understand where I’m wrong.
Below are the parameters in mVolts detected by the laser:
00.00% = 50mV
01.00% = 500mV
10.00% = 5000mV
20.00% = 5000mV
100.00% = 5000mV
below are the RGBL parameters:
$$
$0=10
$1=25
$2=0
$3=0
$4=0
$5=0
$6=0
$10=255
$11=0.010
$12=0.002
$13=0
$20=0
$21=0
$22=0
$23=0
$24=250.000
$25=3000.000
$26=250
$27=2.000
$30=1000
$31=0
$32=0
$38=10
$100=80.000
$101=80.000
$102=80.000
$110=3000.000
$111=3000.000
$112=1000.000
$120=20.000
$121=20.000
$122=20.000
$130=650.000
$131=650.000
$132=200.000
ok
Has anyone had the same problem?
Do you have any advice to help me figure out where I’m going wrong?
I would say first and foremost this is hardware and not software issue.
Lightburn only issues a Svalue command which your machine then translates into a voltage and PWM signal
However, the primarry issue is you are assuming the power scale is linear, when in reality it “should be” but isnt
Usually the bottom 10% and the top 10% of the scale are non linear
In other words, 0 - 10% the laser might not even trigger correctly (in some machines) and in diode lasers nrmally it will be a non linear response, above 10% you start to get a bit of linear response.
90 - 100% theres basicly, on average, no change in power what so ever
I assumed a software problem, I had not detected such a problem in the old version of Ligtburn, I do not exclude the possibility that the hardware was damaged at the same time.
regarding the power scale, I am aware that the relay value cannot be linear with the theoretical value.
My problem is that the laser outputs 100% power, with only 10% set to the level.
Below I correct the voltage values found based on the % of power set:
000,00% = 50mV
001,00% = 500mV
010,00% = 5000mV
020,00% = 5000mV
100,00% = 5000mV
