Overburning when trying to fill with laser

Hello!

I’ve recently built a MPCNC machine with a NEJE 20W Module laser.
Using Marlin on a Ramps board.

Works really good with line burning, tried to use the power scale for Lightburn project found here:

Live Time - Creating A Laser Vector Test Grid

It seems like it overburns when filling:

This is how it looks with the line burning only:

Anyone got any ideas?
