This is a sort of collection of things I´ve found on thingivee to make this conveion to standalone. I wanted to get rid of the alfawise box, and clumsy board. Duet3d Wifi board italled under the bed, along with the PSU. Italled board upside down because bed screws on U20 are way to long. Uploaded s3d profile and retraction test so you can check.
