i have this laser https://www.ebay.com/itm/Engraving-Lase ... SwKA5b2GM-

and if this laser is only on /off or if i can adjust the power by pwm

If you use a separete 12VDC supply then connect 12V - also to 5V0 on the non-isolated outputs group of the AXBB, any of O9 to O17 to the laser Signal IN.

It looks like On/Off only.

On/off, but they wrote 200kHz TTL with high speed isolation which means that you can switch the laser fast with the motion controller (with the laser PWM from the controller) and so you will see avarage power from the laser, or at least you should if the e-bay listing data is true.
