T9 laser picks up power as it moves.

Marco,

Installed a T9 in a full spectrum laser. When I burn anything the power increases as it moves.
How or where do I correct this in the T9 controller? I am moving from left to right.

Thank you
Jim

Disconnect the laser power supply from the T9. Check the pwm pin DC voltage. If it is constant, the problem may be the laser power supply.
