I’m really new to all that laser stuff and I have the most hobby setup you can imagine:
Ender 3 Pro + Creality 0.5w Laser engraver.
So I tried many different software and Lightburn is imho most comfortable one! So I decided to post my issue here.
I try to engrave an image of my son. But all outcome till now is following:
A kind of an noise pattern.
In lightburn under preview I can see a fairly nice picture.
Do have someone any clue what it can be?
Is it just my hardware which is not able keep up?
Thanks a lot in advance!
Hmmm… perhaps it has something to do with the pwm mode. I will change it in the firmware to FAST_PWM_FAN. Let’s see what happen.
It’s getting better!
Propably that’s max I can get out of it.
In Marlin under configuration_adh.h there is a option called #define LASER_SYNCHRONOUS_M106_M107.
With this I achieved above result.
Thanks for your feedback!
Yes, I tried with “adjust image”. Funny is that all my changes of gamma, contrast and brightness hadn’t any effect.
I already “optimized” this image with GIMP. Means indexed colors (1bit) and so on. Maybe thats why my changes hadn’t any effect on the image.
I will try my best to redo with different options. This was made with option grayscale next time i will try it with your mentioned and other options.
Have a nice weekend!
yes, i will stay at round about 300 dpi.
