Building a desktop power supply from an old Creality CR-10
Tried to make a circuit diagram, still learning electronics and how to diagram. It was difficult because most of the components aren’t standard.
Measurements & CAD:
Created the initial design for the housing with ports for an AC plug and switch (back) + 2 bannana jacks, 2 potentiometers, and a digital multimeter (front).
Disassembly:
Opened up the CR-10 control box and had a look at the insides. Removed the power supply and all relevant wiring including some fans. Then set up a simple test circuit with an Arduino and stepper motor to make sure everything still worked.
Spent around 2 hrs working, still don’t really understand how the time tracking works.
