Is there any settings to avoid "over threated" edges when doing a png?

Is there any settings to avoid “over threated” edges when doing a png?
The outer edge gets much darker as the laser makes a turn to do a new line…

Laserweb 4, ACAN diode laser, cnc shield 4

If you use GRBL firmware, configure M4S0 on START GCODE instead of M3.
M4 adjusts laser power related to accelleration/decelleration.
If you don’t use grbl, then try the OVERSCAN feature in the operation settings.

I am on grbl and the gcode start is M4 S0 :roll_eyes:

Change TOOL ON to M4 also.
