@pauledd You got it ! Same idiot issue. I put the board on the right pins and it works now.
Sometimes more than 2 eyes and a good reactive forum helps.
Thank you very much guys !

That's from the 2.03 release notes, which is the version you were running before, wasn't it?

Laser mode: for safety, the G1 S parameter is no longer sticky by default. You can make it sticky by adding parameter S1 to the M452 command.

From 2.04

In Laser mode, if sticky laser power mode is selected, the power set by the S parameter in a G1 command is remembered across G0 moves to the next G1 move

M452 C"!exp.heater3" R255 F1000 ; enable LASER mode

You're missing the S1 on your M452 command to enable laser mode.
