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 applied to any axis of a CNC-ready Sherline machine that has stepper motor mounts already installed. It is designed to work with Sherline inch machines only at this time.
The linear motion controller has its own keypad and built-in computer. It comes with its own power supply, a #23 frame size stepper motor, connecting cable and complete instructions. 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 (blocks) 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. (Available in inch version only at this time.)
NOTE: If you wish to apply CNC control to an axis of a Sherline machine that does not have a stepper motor mount, see P/N 8850
