      This Is new to me, while i am quite able to do my Hard Parts machining/Conversion. and I do know some CNC milling G-code. The duet is quite a lot different than what i am used to working with.
      Right now i am in the final stages of my CubePro Redesign / Rebuild, and soon it will be programming time. can some one look at my component list Below. I have a feeling i may be light on power supply wattage. and is it a problem that my X and Y Axis, oriental motors are higher voltage than the rest? or is that just a matter of the max current setting?
      Thanks in advance.

        To calculate the total wattage you need, see https://duet3d.dozuki.com/Wiki/Choosing_the_power_supply#Section_Total_power_needed. Don't forget to include the power draw of the LED strips.

          I was hoping you would say that, as room in the electronics bay is close to being 100% full! this is the original 3D systems PS, and to get something bigger would be another 50mm x 25mm. I have moved all the electronics from the inside bottom to the outside rear.
          Thanks

            I edited my original reply, because although 200W would normally be more than enough for a dual-extrusion printer that uses an AC mains bed heater, I don't know the power draw of the LED strips.
