What is the reason to use 24v with the jackpot and LR4? I have a 12v 30a meanwell power supply I used on my mpcnc, and was hoping to use it on my LR4. Any issues with that? The board looks to support the range, just not sure what I would be giving up going lower. Thanks

12 V can do fine. I used 12 V on my LowRider v2 and on my LowRider v3. I did finally start using 24 V when I built LowRider v4. I think the only advantage with 24 V is that you can do faster Rapids with the machine. But to get those faster rapids, you have to tweak a parameter or two. If you don’t change the Gcode travel / jog parameters in your CAM software and tweak your kinematics regarding inertia in your Jackpot config, then you won’t see really any difference between 12 V and 24 V.

12v should be fine, based on the jackpot page it says 19 watts for the board and gives the example of 24v at 0.8amp, 19 watts for 12v should be 1.58amp for the board (someone correct me if I’m wrong please) don’t forget you’ll still need the power for the steppers as that would be just the board and esp alone

The steppers get powered from the board though right? You just mean I need enough amperage for the board and steppers both? That can all run on the 12v input on the board right? Figured surely 12v 30a would be enough for the steppers as well.

Yea, that’s way more than needed. The power supply sold in the V1 store is 24v @ 2.5 amps, so 60 watts. You’ve got 300 watts more than that.

Thanks, I wasn’t seeing an amp or wattage of the one sold, so couldn’t really come up with solid answers. Appreciate everyone’s help! Rather stick with 12v so I can use LEDs and fans in 12v without having to step down.

The stepper drivers are constant current. And the resistance isn’t constant. So total power isn’t the only consideration. But 12V will be just as rigid as 24V at low speeds.

That’s what I wasn’t to sure if it included or not when the page said 19 watts or not, based on its minimum stated, thanks!

So I’ll start out with the 12v supply, and if I need more speed, I can upgrade it later. Thanks for helping me figure out what the higher voltage is used for.
