The board is the Crealty Ender 3 S1 Pro stock 32-bit MCU. It is running some version of Marlin from what I understand.
There is not any PWM signal currently when asking for any power level. 24V power only.
Creality is sending a replacement the motherboard.
Both lasers are from Creality amd made for this unit. (they also work on other systems, but these units are specifically offered on this platform.)
I should have a new microcontroller board to swap in a week or so I would think and give it another try.
