What is the POT for

Ok. Dumb question. What is the potentiometer for?

The L7 has one to adjust the weak power, and the motor drivers have one each to adjust current.

The Mana SE did away with the weak button and pot.

On the L1 board there is a jumper for 12 Volt or adjustable voltage for the laser, and the pot is to adjust this voltage.

Thanks. I may have to play with it. Sometimes my weak laser works, sometimes it doesn't. The bane of an L7 8)

I posted reverse engineered schematics for the L7 about 6 months ago. Take a peek and let me know if the resultant schematic looks correct

I will double check but I think you sent me those schematics. If not, it was for the L6

the board mana se have a laser connector with tre contact +12 gnd pwm, As it connects to a two wire laser?

Yes? The mana has a two wire connection labeled motor. I believe it works the same at as the laser

The "motor" connector is a switched 12VDC (using the MOSFET) the same as the laser connector on the older boards (L7).

The "laser" connector has a constant 12VDC and a TTL signal (S-pin) to control the laser.

If your laser has a TTL input you will want to use the laser connector but if it's the older 2-wire module you need to use the motor connector.
