Sorry of this is a stupid question, but add a potentiometer to do what?

I was confused too but now I see...
With these particular drivers, no. The LDD drivers are controlled with a PWM signal rather than a 0-5 or 0-10V source. If you got a simple IC, like a 555, you could add a potentiometer to that to vary the PWM signal to the drivers. It's not difficult to implement if you want to forgo a controller. There are simpler controllers than the Jarduino if that's what you are looking for. I use a Typhon but will hopefully be experimenting soon with a cool new controller that Spencer at Blue World Victoria is working on.

Glad you got it figured out. I'm out camping and doing this on my phone with my big dumb thumbs
 Trying not to have to put long posts up, lol.

Yup, I've got 4 LDD-1000 running off one pwm pin. Just remember to tie your neutrals together on your input sides.

Took a risk and its worked! The ps that i have is very noisy. Looking for 48v ps. Will this works for the LDD drivers?
