Hello, Can anyone advise me please. I have a SLB ext. I don’t need to power the motors from the board as I have separate power supplies.
I know it says I need a 24v 12amp supply but what’s the minimum amps needed to power the board.
I have tried a 24v 3.2amp but still stone dead.
I’m a bit reluctant to use a 24v 12amp supply just to power the board. I don’t know maybe this is what it needs?
I understand what you are saying, but I don’t know the power requirements for the SLB. If you have the recommended supply, give it a try. The SLB won’t draw any more power than it needs.
Also, there is a small power switch on one end of the SLB. It’s easy to overlook. Make sure it’s on and the EPO is in the out position.
Thanks Paul. Good shout I was being cheap. I’ll get a 24v 10amp and keep it separate from the safety circuit power supply.
Hey thewnglisman,
Have you connected the estop button to the slb? It wont do much without it.
I think 3 amps is more that enough to power the basic functionality of the board.
What beast are you erecting with that slb? Oo
Thank you… I have not tried with the Estop plugged in…
I shall try 
…
Nope still all dead with the Estop.
Tried 3.8amp with my bench top supply and still nothing.
I’ll order a 10amp supply and try that maybe… Yep been confirmed 10amp minimum.
I will also need to wire in my Estop circuit into the SLB Estop to make it common. Not looked at it yet but shouldn’t be too hard.
I have HLTNC nema23, 3Nm, hybrid stepper motors with built in closed loop servo drivers. Going to run them at 40v.
I also have some nice IHSV57 180w, closed loop servomotors with built in drivers which I will try to install and set up after I’ve had a play with the HLTNC stepper motors.
