nema 23 is used in an analog clock. This “antique” automatic correction analog clock was designed by Instructables user gzumwalt.
Previous clocks used spring-driven mechanisms, while gzumwalt clocks used Adafruit Feather ESP32 and nema 23. Before assembling printed parts, test their suitability and file or polish them as much as possible to promote smoother movement. Make sure that all edges in contact with the printer plate are smooth.
Special attention should be paid to moving surfaces, such as gear teeth, and eliminating any “dirt” in plate making. For threaded parts, taps and dies may come in handy, mainly because the clock relies on threaded parts. Once you’ve done this, here’s a general overview of the assembly steps:
1.The reed switch enters the 3D printing bracket. This component is fragile and needs to be handled with care. For example, only bent reed switch wires use high-quality pliers to reduce the possibility of fracture.
2.Adafruit demonstrates how to use socket connectors to assemble featherboards.
3.Connect Adafruit feather plate to reed switch and nema 23 controller. You will weld, but also use screws and nuts to connect these three components.Most importantly, you need to know which wires go where during welding, because you can’t confuse polarity.
Keep in mind that the Adafruit feather board and nema 23 controller will be attached to the side that cannot accommodate the gears.
