Octopus Pro 1.1 h723 fried

Ok so I'm stupid as fuck. I tried to swap Z drivers with power on, pressing emergency stop wasn't enough to kill power to the drivers as I thought. I'm gonna get a new board but for the fun of it I'll try to repair it. Issues/symptoms : Motor7 generates a error as soon as the stepper is enabled (FORCE_MOVE command) Motor6 DIR signal seems broken, stepper can only move in one direction regardless of instructions and inverting dir pin in config does nothing. I checked schematics and I'm currently suspecting U24 as it handles both M7 enable/DIR/STEP and M6 DIR. Thoughts?

Do you have a hot air gun? Getting multi pin ics off can be tough without

Yes I have a hot air station. Waiting for components ATM Replacing U24 solved the issue

However some more stuff on the board are damaged like many endstop inputs so I had to move the VAOC Z endstop to X endstop that where free.. Everything else seems to work. Reading the schematics it looks like the inputs goes directly to the mcu. Not sure it's worth changing it for 10€. I'll probably just stick with my custom assignment of Z endstop
