My remapping function of power isn't satisfying yet. I must say that i didn't take the easiest photo. I made a quick user interface (Python).

Lessons Learned :
To avoid white lines caused by a mismatch between the requested travel distances and the minimum step resolution allowed on an axis, I implemented a step-based logic where the commanded distance is computed by multiplying the number of Y-axis steps by the axis counts-per-unit value.
The same resolution was initially used for the X-axis motion; however, the system was unable to keep up with the resulting instruction rate, causing the feed rate to drop to 2400 instead of the requested 3000. As a result, the resolution had to be reduced.

Here's the first release of my Gcode converter, AliG : https://github.com/MoMo830/AliG/releases/tag/AliG

Feek free to comment.

A small example, once settings are correct.

Excellent progress.
