Cycloidal Reducer for NEMA 17 Stepper

In addition to the aforementioned files, you will need to procure the following ancillary components, including set screws, bearings, dowel pins, and standard screws, among others. The provided print files have been meticulously optimized for tolerance and should pose no issues during printing, with the exception of H2D. For those utilizing H2D, please note that its tolerances can be quite variable, ranging from approximately 0.4mm to 0.2mm, and may require manual adjustment. For CNC requirements, the two crankshafts can be processed through JialiChuang's complimentary CNC service, while all other parts can be acquired from QuanZhou. By leveraging QuanZhou's promotional coupons, it is feasible to keep the total cost, inclusive of all hardware, under 70, though some strategic purchasing may be necessary. Installation Notes: The two cycloidal discs are designed for perfectly symmetrical placement; therefore, no alignment markings have been provided. During assembly, proceed with precision: first insert the 4mm diameter locating pins, then secure the top cover, and finally, install the set screws. Regrettably, I currently lack the time to produce an assembly video. However, the assembly process for this category of gearbox is generally quite similar across models, so please endeavor to explore and understand it independently. I intend to complete a comprehensive assembly video when my schedule permits. I wish you all a gratifying assembly experience and anticipate seeing the diverse applications you discover for my creation. I eagerly await your insights and the unveiling of your completed projects! May your days be filled with joy!
