Hello
Please i need your help , about the Deskcnc 2end Generation controller board
i woud like to upgrade my cnc router with a 6watts laser engraver that use TTL/PWM port .PLH3D-6W-XF Engraving Laser Head
https://optlasers.com/plh3d/plh3d-6w-xf-laser-head
i want to ask if his bord have a PWM output to drive this laser head.

PLH3D-6W-XF Engraving Laser Head
laser diode Control Inputs
The laser head has two separate controls. Input #1 accepts 0 - 5V for analog power modulation. Input #2 accepts 0 - 24V for TTL/PWM and turns on the laser when the voltage exceeds 2.5V. (Input #1 can also be used for PWM if #2 is dedicated for TTL only.)
Best regards.

The Deskcnc 2end Generation controller board does have a PWM output. This signal can be used to control Spindle RPM or Laser Power.
There is a setting in the Options menu to choose between Laser and Spindle, as well as if PWM signal needs to be inverted.
In your case, I would ting you want to go with #2.
