How would u wire up the board to power when using an external ps but keeping the original for the laser ps?

2

Stepper and endstops wired into external PSU. Can you identify those?

3

I’m using C3D mini board

So you have already everything connected to it, the just change the board input voltage to the external PSU

@Ariel_Yahni_UniKpty what about the power for the laser? It’s still powered by the stock psu?

@William_Kearns ​ laser power itself never goes through the board ( any board ) that goes directly to the tube

@William_Kearns , please see the C3D Documentation link. I posted a lengthy step-by-step instruction how to wire two external drivers and steppers. The wiring will be the same as what you are trying to achieve here.
