CNC Linear Controller – X/Y Axis

Clear selection

Product Description

This linear controller comes with a stepper motor mount for machines that are not CNC-Ready. This stand-alone controller is programmable from its own keypad and controls the function of the stepper motor to which it is attached. The stepper motor may be mounted to the crosslide of a Sherline lathe, and the X- or Y-axis of a Sherline mill. (A separate kit is available for the lathe leadscrew as P/N 8870 [15″] or 8880 [24″].)

An 8-pin mini-DIN cable can be used to connect multiple units in a “daisy chain”. The units can signal each other to work in sequence, allowing multiple movements to be accomplished without the use of a computer or master CNC controller. They can also be used in conjunction with existing CNC controllers. The controller is user-programmable with two separate programs of up to 40 operations each. In each block, you can control distance, direction, speed and whether the program pauses or proceeds to the next block.

The linear controller can also be “daisy chained” with Sherline’s rotary controller (P/N 8700) to achieve combinations of rotary and linear movement in sequence. This makes it easy to set up for relatively sophisticated operations like cutting gears without having to know anything about CNC programming beyond what is entered from these simple keypads

Items included with the CNC Linear Controller:

  • Linear Controller w/Keypad
  • Power Supply
  • #23 Frame Size Stepper Motor
  • Cables
  • Stepper motor mount
  • Dampened coupling
  • Preload nuts
  • Drill guide block and complete installation and use instructions

NOTE: The power supply included with this indexer (linear controller) is intended to operate only on 115/120 VAC, 60 Hz (38 W) current. For countries operating on 100, 220 or 240VAC and/or 50Hz a transformer will be required. As an alternative, this power supply outputs 24VDC, 1 Amp (1000 mA). If you can purchase an appropriate power supply that operates on local current and outputs 24VDC, 1A current, it could be used to power the unit instead of the one supplied. Sherline Products does not provide a 220V power supply or transformer.
