This document outlines the assembly and installation process for the BobsCNC Z-Spindle Kit, designed to enhance the functionality of BobsCNC E3 and E4 CNC machines by allowing the integration of various routers and spindles. The kit provides a versatile mounting solution, enabling users to adapt their CNC machine for different routing and carving tasks.
The BobsCNC Z-Spindle Kit serves as an adapter system, allowing users to mount a variety of routers and spindles onto their BobsCNC E3 and E4 CNC machines. By providing interchangeable mounts, the kit enables the use of popular routers like the DeWalt 611 and Makita RT0701C, as well as generic 52MM air-cooled spindles. This flexibility is crucial for users who require different power, speed, or tool-holding capabilities for their projects. The core function is to securely hold the chosen router or spindle, ensuring stable and precise operation during CNC machining. The kit's design focuses on modularity, allowing users to switch between different router types as needed, thereby expanding the capabilities of their existing CNC machine without requiring a complete system overhaul. The Z-Spindle Kit essentially acts as the interface between the CNC machine's Z-axis carriage and the cutting tool, translating the machine's movements into precise cuts and engravings.
The Z-Spindle Kit is designed for straightforward assembly and integration with the BobsCNC E3 and E4 machines. The kit includes a series of laser-cut wooden components, such as frame mount supports, Z-frame components, and various spindle mid and top mounts, along with necessary hardware like machine screws, nuts, and zip ties. The assembly process begins by transferring the washer and nut assembly from the old mount to the new Z Frame Supports, securing it with a zip tie and additional screws and nuts. This initial step establishes the foundation for the new spindle mount.
Subsequent steps involve attaching the Z Spindle Bottom Mount (A) to the Z Frame, followed by the Z Spindle Mid Mounts (B) and (C). A key feature of the mid mounts (B & C) is their slotted design, which allows them to slide towards the frame. During initial assembly, these mid mounts are intentionally left loose. This "loose" state is critical for the installation of the router or spindle, as it creates an opening for the tool body. Once the router/spindle is in place, these mid mounts are tightened to firmly secure the tool. This adjustable clamping mechanism ensures a snug fit for different router body diameters, accommodating slight variations between models.
The Z Spindle Mount Top (D) and Z-Spindle Top Mount (E) are then attached, completing the structural framework of the spindle mount. The kit also includes frame mount supports that connect to the spindle top mount, further reinforcing the entire assembly. The use of M4 and M16 screws and nuts throughout the assembly ensures robust connections. The instructions emphasize not fully tightening certain components until the router/spindle is inserted, highlighting the importance of sequential tightening for proper fit and function. This staged tightening process is a deliberate design choice to facilitate easy installation and ensure optimal clamping force on the router/spindle.
The final step involves inserting the chosen router or spindle into the assembled mount. Users are reminded to ensure the mid mounts are loose to allow the router body to slide in. Once the router is in position, the four screws holding the Z-Spindle Mid Mounts (B & C) are tightened to secure the router firmly. This clamping action is essential for preventing any movement or vibration of the router during operation, which could compromise cutting precision. After the router is secured, the complete Z Carriage, now equipped with the new spindle mount and router, is reinstalled onto the CNC machine according to the main assembly manual instructions. This integration ensures that the new router/spindle is properly aligned and ready for use with the CNC system.
The primary maintenance feature highlighted in the manual pertains to the threaded rod assembly. Users are advised to apply dry lube to the threaded rod once a month. This recommendation is specifically for the dusty environment typically created when operating CNC machines like the E3 and E4CNC. Dry lubricants are preferred in such environments because they do not attract and hold dust and debris as much as wet lubricants, which can lead to abrasive wear and premature failure of moving parts. Regular lubrication of the threaded rod ensures smooth and consistent movement of the Z-axis, which is crucial for maintaining cutting depth accuracy and overall machine performance. This simple, routine maintenance step helps to prolong the lifespan of the threaded rod and associated components, ensuring reliable operation of the Z-spindle kit over time. The emphasis on dry lube underscores a practical approach to maintenance in a workshop setting where dust generation is inherent to the machining process.
