Sherline Rotary Table CNC Conversion
thingiverse
I acquired a manual Sherline Rotary Table (#3700) that I wanted to convert into a CNC machine. This design is for a frame that secures a Stepper Motor to the Rotary Table's Worm gear's shaft, along with a spider coupler to transmit rotary forces from the stepper motor to the shaft. You will need PLA material (or ABS) and TPU for the spider coupler. Apart from the 3D printed parts, you will also require: 1) A stepper motor - I used a 17HS4401 NEMA 17 Stepper Motor 2) 3 x M3x40mm screws to secure the mount bracket to the mount holdfast and then to the motor frame 3) 4 x M3x5mm screws to mount the stepper motor to the motor frame 4) 2 x M3x10 screws to secure the mount and shaft couplers to the stepper shaft and worm gear shaft 5) 7 (or possibly fewer) M3 nuts
