Hi Captain,

Thanks for the very clear description. My procedure was different, I used thr CAD package to export a high resolution BMP file (or JPG), and used the Eleksmaker software to "scan" it as a picture.

What I will play with is the opposite of warpspeeds suggestion: De-focus the laser a bit and bring the travel speed down. That way it wil carve slightly wider channels through my black paint, and may result in wider gaps (fewer shorts after etching, or while soldering).

I will checkout the "laserweb" software. That seems a nice piece of code.

By the way, did you ever update the firmware on the Eleksmaker ? There apparently is a newer firmware that is more accurate, and has laser power adjustment(PWM) when the traction motors slow down for a corner. I tried that new code (I recall it is version 1.12 or so), and it improved, but was incompatible with the Eleksmaker Windows software (that software checks for version 0.95, and refuses to work otherwise). I manually edited the 1.12 firmware to give out version 0.95. And manually edited some of the parameters.
I also saw in a Youtube video that there are better stepper motor driver, that have improved microstepping. It could improve (if you have mechanically tuned all play out of the system).
