The final check before diving into fabrication is to verify that all of the assumptions I made earlier in the design process are still accurate, or at least conservative. If not, I may need to iterate something again (hopefully not...
The final mechanical system to design is the mounting structure that attaches the spindle to the 3-Axis motion system. The most important features are the provisions to allow the tramming (slight X/Y tilting) required to align the spindle perpendicularly to...
So far most of the engineering and analysis has been done on the moving subassemblies within the router (gantry beam, gantry carriage, spindle carriage). However, the structure that supports all of the moving subassemblies is just as important to the...
The control system for a CNC router encompasses not only the numeric controller that plans the motions, but also the motor drivers, power supplies, limit switches, circuit protection, and cabling that connect them all together. From voltages to protocols all...
