The control starts up in Incremental jog mode. In order to jog the axes in continuous movement, you need to press the INCR/CONT key to switch from incremental to continuous jog mode.

Optionally, you can plug in a USB mouse and use it to navigate the program text and the menus in the text editor.
The Intercon conversational programming feature will not be useful for writing Cylindrical Grinder programs. You will need to write your programs in CNC G codes.
The X axis moves the grinder in and out, determining the diameter of the part.
The Z axis moves the carriage left and right, along the length of the part.
Every program should start with a G98 code before any feedrate movement. This will select feed-per-minute feedrates. Feed-per-revolution is not available on this machine because it lacks a spindle encoder.
Use X and Z to command the axes to move to specified positions, measured from the part zero position you have set.
Use U and W to command the X and Z axes to move incremental distances, from wherever the previous move left off, without regard to the part zero position.
Use G1 and a feedrate to do straight-line feedrate movement to a specified position or by a specified distance.
Use G0 to do rapid positioning moves.
Use M105/Z P1 to move the Z axis in the minus direction (carriage right) until it trips the minus shuttle switch.
Use M106/Z P2 to move the Z axis in the plus direction (carriage left) until it trips the plus shuttle switch.
Use M3 and an S value to start the workpiece spindle rotating at the requested RPM. Use M5 to stop the workpiece spindle.
Use M13 to start the grinder spindle. Use M15 to stop the grinder spindle.
Use M41 through M48 to select the speed of the grinder spindle, in 8 steps. M41 is the slowest available speed; M48 is the fastest available speed.
Use M8 to start the coolant. Use M9 to stop it.
Use G28 U0 to move the X axis all the way back, without having to know what X coordinate that may be.
The Aux1 and Aux2 keys and LEDs in the the upper right section of the jog panel can be used for program control. You can turn the LEDs on and off by pressing the keys. You can also turn the LEDs on and off with programmed M functions (to choose a default mode). You can use IF/THEN and GOTO commands in the part programs to perform different operations depending on whether an LED is on or off.
The suggested use is to have Aux1 select infeed while grinding, and to have Aux2 indicate that the part or feature is finished. Programs would generally check the state of the Aux LEDs at the ends of the part, before turning around.
Use M61 to turn on Aux1 in a program (enable the infeed request).
Use M60 to turn off Aux1 in a program (cancel the infeed request).
Use M63 to turn on Aux2 in a program (enable the end request).
Use M62 to turn off Aux2 in a program (cancel the end request).
The workpiece spindle is controlled by the Spindle Control keys in the upper left section of the jog panel.

The MPG handwheel pendant can be used to jog the axes during setup operations, and it can also be used to "offset" the X axis during a program cycle.
To use the MPG in a normal jogging mode (not affecting the offset
amount for the X axis), turn the jog panel Aux4 selector off.
With Aux4 off, you can use the MPG to move the X and Z axes as needed for setup and preparation. Turn the axis selector on the MPG pendant to "X" or "Z" as needed, and turn the increment selector to "x1", "x10", or "x100" as needed.
The x1 increment is for fine slow movement (0.0001" per click, or 0.010" per revolution). The x100 increment is for coarse fast movement (0.010" per click, or 1.0" per revolution).
To use the MPG in an Offset mode during a program cycle, turn
the jog panel Aux4 indicator on and turn the axis selector to "X",
before you start the program cycle.
In the Offset mode (moving X, with Aux4 turned on) MPG handwheel movement adds to a hidden offset value which is added to programmed X axis position. The X axis will, therefore, move to whatever positions it was programmed to move to, offset by the additional amount set with the MPG handwheel.
The MPG Offset amount affects all X axis movement, even after the program cycle ends. The only ways to remove the MPG X Offset amount are to dial the offset back to zero, or to shut down, power off, and power back up.
To dial the X Offset amount back to zero:
If, when you try to do the MDI move to a chosen position, the control reports "907 X axis travel exceeded", it means that the control cannot move to that position (plus the offset) without going beyond the axis travel limits. This probably indicates an unusually large offset amount. Try smaller numbers until you find one that works.
These programs use local variables and various advanced macro features.
The variables allow a single program to cut parts with different dimensions, simply by editing the dimensions at the top of the program (above the double line).
The IF/THEN and GOTO features are used to repeatedly loop back and forth across the part, and provide for optional infeed.
Manual infeeds can be done with the jogging keys and/or MPG handwheel, but only while the control is waiting at a programmed M0 (pause and wait for CYCLE START).
This program grinds a straight diameter, with optional manual infeed at each end. It assumes that there will be several back-and-forth passes between infeeds, so it automatically cancels the Aux1 infeed request after each use.

This program grinds a straight diameter, with optional manual infeed at each end. It assumes that there will be an infeed at every turnaround, so it automatically enables the Aux1 infeed request at program start, and leaves it on. The operator can cancel it by pressing the Aux1 key when he wants to "spark out".
