CNC Linear Controller with Stepper Motor
This stand-alone controller is fully programmable via its integrated keypad and directly controls the stepper motor to which it is connected. The stepper motor can be applied to any axis of a CNC-Ready Sherline machine.
An 8-pin mini-DIN cable allows multiple controllers to be connected in a “daisy-chain” configuration. Controllers can signal one another to operate in sequence, enabling complex, multi-axis movements without the need for a computer or master CNC controller. The system can also be used alongside existing CNC controllers. Each controller stores two independent programs, with up to 40 operations per program. For each operation, you can define travel distance, direction, feed rate, and whether the sequence pauses or proceeds to the next step.
The linear controller can also be daisy-chained with Sherline’s rotary controller, enabling coordinated rotary and linear motion. This allows users to easily perform advanced operations—such as gear cutting—without requiring CNC programming skills beyond simple keypad inputs.
Included with the CNC Linear Controller:
Linear controller with keypad
Power supply
#23 frame size stepper motor
Cables
Complete instructions
Note: To add CNC linear control to an axis on a Sherline machine that does not have a stepper motor mount, see P/N 8850.
Power Supply Compatibility:
The included power supply operates on 110–240 VAC and automatically adjusts for global use (220–240V). Earlier versions of this product shipped with a 110 VAC-only power supply.
Mill Collet Set
Sherline milling collets are specifically designed for use with the Morse #1 internal taper, which is standard on both the Sherline lathe and vertical mill. Due to the shallow angle of the Morse #1 taper, tightening the drawbolt results in significantly greater clamping force compared to WW collets. For this reason, we recommend using these milling collets to securely hold miniature end mills (with 3/16" or 1/4" shanks), #1 and smaller center drills, Dremel® bits (1/8" shank), and a variety of other small cutters.
Inch Mill Collet Set: 1/8", 3/16", 1/4"
Metric Mill Collet Set: 3 mm, 4 mm, 6 mm
Note: Tools held in these collets must have a shank diameter within .001" of the stated size. Because of the shallow taper, the collet will remain tight in the spindle even after loosening the drawbolt. To release it, back the drawbolt out a few turns and tap it lightly to free the collet.
⚠️ CAUTION: When tightening the collet drawbolt with a Tommy bar, be careful not to insert the bar too far into the spindle. Doing so can damage the collet’s taper area. The red arrow in the image below shows an example of this type of damage.
Stepper Motor
Sherline stepper motors feature shafts at both ends, allowing for manual control via a handwheel, if desired. Flats are ground onto each shaft to accommodate set screws for the handwheel and coupling. For use with a Sherline motor mount, ensure that the shaft entering the coupling has a flat machined or ground onto it where the set screw secures it. Failure to do so may damage the shaft, making the coupling difficult to remove. For non-Sherline applications, the flat may not be necessary.
Powerful Dual-Shaft Motors
P/N 67127: This motor comes pre-wired with six leads in a connector that plugs directly into Sherline's linear or rotary controllers. Both our CNC system and driver box include four pre-wired cables with 5-pin plugs that match the P/N 67127 stepper motor. Simply plug each stepper motor into the corresponding axis cable for an easy setup.
P/N 67130: This motor features six raw wire leads, and does not include a connector, so that it can be used with non-Sherline controllers that have a different pin configuration.
Note: Due to the lack of standardization in the industry, wire colors can vary between suppliers. If using a connector not supplied by Sherline we recommend using a continuity checker to identify which wire connects to each pin on the DIN plug. Typically, the black and white (or tan) wires are connected to the center pins, but other colors may vary. See our specifications sheet for wiring diagram.
