I just installed a new power supply. 80W-90W PWM CO2 Laser Power Supply
The max output is about 8mA. I've verified the PWM IN voltage to be 5V.
The pot is fully clockwise.
Is there anything else to adjust or test?

It's installed in an FSLaser Pro. Connections to L, WP, G and IN.

If the laser tube and mA meter are good, could be the laser power supply is in 220V mode. If you have 220V outlet, you may power the laser power supply using 220V and try. If it is the case, you may return the power supply and we will ship you one with 110V mode.
