Hi, all,

Currently, I've got a 3-axis Keling setup, http://www.kelinginc.net/ThreeXCNCPackage.html, and I want to upgrade to a 4th axis on my machine (using the same 4030 driver and KL23H286-20-8B 425oz stepper). Does anyone know if the included PSU will handle the added load of the 4th driver/stepper? If not, which should I go for as a replacement?

Thanks!

Thought I should post an update on this - I decided to stick with my current power supply, and try things out. I haven't done any major work with my machine yet, but the current PSU does seem to be handling the load of 4 motors and the fan.

However, I'm writing my own software to control the machine, and tend to run only 2 motors at any given time, just because of the way I'm doing things internally. I am able to run all 4 at once, but I've only tried for very short periods.

Your mileage for this PSU and 4 motors may vary, but things look positive so far.

You can try it first. If it is not handling the motors, you can update to KL-3815, 38V/15A
