Sherline’s single-axis controllers are designed to drive the stepper motor on any individual axis of a lathe or mill—no separate computer or driver is required. Each controller features an integrated computer chip within the keypad/control unit, allowing you to operate the motor directly from the keypad or enter simple programmed sequences—no G-code knowledge needed.

You can program parameters such as direction, travel distance, feed rate, and whether to pause between operations or proceed automatically to the next step. The controller can store up to 40 steps (each with four parameters) in either of two user-defined programs. Multiple controllers can be linked via cable to synchronize movements or can be connected to a larger CNC system using “sense” and “acknowledge” signals to coordinate actions within a CNC sequence.

Stepper Motor Mounting & Drive System

Each stepper motor mount includes dual ball bearings with a preload nut to eliminate endplay. A dampened coupling connects the motor’s 1/4" diameter shaft to the leadscrew. The dual-shaft stepper motor also allows for manual operation using the provided handwheel. The controller employs micro-stepping for precise, smooth movement.

Mounting Options

• From the Bottom: Four 1/4-20 holes on 2" centers in the base for mounting from below.

• From the Top: If bottom access is unavailable, use the included four angle clamps that fit into the perimeter groove of the base. Drill and tap the mounting surface for the included 10-32 socket head cap screws. Use all four clamps for maximum stability.

Included Components (Linear Machine Slide with Programmable Controller)

• Single-axis slide with your choice of 8", 13", or 18" table

• Linear controller with integrated keypad

• Power supply

• NEMA #23 frame size stepper motor

• 1-5/8" handwheel, graduated in .001" increments (inch) or .01 mm increments (metric)

• Cables

• Complete instructions

Power Supply

The included power supply operates on 115/120 VAC, 60 Hz (38 W). For regions with 100, 220, or 240 VAC and/or 50 Hz power, a step-down transformer is required. Alternatively, you may supply 24VDC, 1A (1000 mA) from a compatible local power source. Sherline does not offer a 220V power supply or transformer.

Weight Capacity

The slide has a weight capacity of approximately 10 lbs, depending on table length and load placement. For an 18" table, limit off-center loads (at the table end) to no more than 10 lbs. Heavier loads may be supported if centered near the base.

Duty Cycle & Maintenance

Under heavy, continuous use, you may observe wear on the anodized dovetail surfaces after one year (approx. 2080 hours). The slide remains fully functional, but regular lubrication with light oil is recommended to maximize lifespan.

IMPORTANT: Do not use WD-40 for lubrication. It will strip the anodized coating.
