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.
The Machine Home position is fully X+ (cross slide forward) and Z+ (carriage right).
You cannot home the machine with the tailstock advanced. Avoid shutting the control down with a between-centers job in progress.

Tools and offsets are numbered 1 through 99. Any offset number can be used with any tool number. However, for simplicity you should use matching tool and offset numbers.
I recommend measuring tool Z offsets relative to one of the tools to be used on the current job, and measuring X offsets relative to an arbitrary "imaginary" reference.
The procedure for this may be found at http://www.cncsnw.com/OLEL.htm, as "Method 3".
The machine has a safety switch on the chuck cover. The chuck cover needs to be fully closed for normal spindle operation.
If you inadvertently leave the cover open, then either try to start the spindle manually or try to run a CNC program which starts the spindle, the control will display an "8081 Chuck Guard Not Closed" error message and cancel the CNC job.
The apron control panel includes electronic handwheels for manual movement; and buttons for manual spindle start/stop/reverse control.
The electronic handwheels must be enabled using the MPG button on the console jog panel.
The handwheel rate is controlled by the x1, x10 and x100 jog increment buttons on the console jog panel.
The machine has a three-speed headstock, with a manual shift lever.
There is no direct feedback to tell the CNC control what gear range the headstock is in. Therefore you need to use the "LOW GEAR", "MID GEAR" and "HIGH GEAR" keys on the console jog panel to tell the control what range you have selected.
Optionally, you can include M functions in your CNC programs, to provide a reminder of when to shift ranges.
Gear ranges and M functions are as follows:
| M43 |  | High Range (500-2200 RPM) |
| M42 |  | Mid Range (150-660 RPM) |
| M41 |  | Low Range (10-180 RPM) |
Spindle start, stop and reverse are controlled by automatic M functions when Auto Spindle mode is selected. Start, stop and reverse are controlled by jog panel keys and the buttons on the apron panel when Manual Spindle mode is selected.
Additionally, the Aux4 key on the console jog panel can be used to jog the spindle during setup (e.g. to bring the chuck key socket around when in low or mid gear). The spindle jogging speed is 15 RPM in low and mid range, and about 50 RPM in high range.

The PLC program can generate the fault messages listed below, in addition to those found in the Centroid operator's manual.
You can use the PLC Diagnostic display on the console to view some of the Centroid PLC input and memory locations mentioned with these error and fault conditions. At the control's main screen, press Alt-I to activate the PLC Diagnostic display. Press Alt-I again to dismiss it.
Each page of the Diagnostic display shows four rows of red and green dots: the first row shows PLC inputs 1 through 80; the second row PLC outputs 1 through 80; the third row PLC memory bits 1 through 80; and the fourth row PLC program stages 1 through 80.
You can use the arrow keys to move a highlight box over any of these locations. The name of the highlighted location will be displayed in the center of the screen below the red and green dots.
For example, in the illustration above the highlight box is on Output #42: The dot below the 2, to the right of the superscript 4, on the second line. The name in lower center tells us that this output is called "OrientPinInSol".
Below the four rows of bit status information are ten numeric ("word") variable values, labeled W1 through W10. Some of these variables also hold useful status information, described with the error and fault conditions to follow.
There are multiple pages of Diagnostic data. With the Alt-I diagnostic display showing, you can use the F12 and F11 keys to scroll right and left. For example, pressing F12 once will shift to the page showing inputs and outputs 81 through 160, and word variables W11 through W20.
Messages with 9000-series message numbers are Faults. After resolving the problem, you must press and release the Emergency Stop button to clear a Fault.
Messages with 8000-series message numbers are Errors. Errors will cancel the program cycle and stop the spindle and coolant, but they do not then need to be explicitly reset.
Messages with 5000-series and 2000-series message numbers are Warnings and Informational Messages. They do not cancel the cycle or require any action to reset.
The control detected an internal error in processing the PLC logic program.
Report this error to your dealer, along with the values from W14 and W15. Also report what function the machine was performing when the fault occurred.
You must shut down and cycle the power to clear this fault.

The CNC program, in combination with the current Spindle Speed Override setting, has requested a spindle RPM lower than the minimum allowed RPM set in the Control Configuration.
No action is required, but be aware that the spindle will be running at the minimum allowed RPM, and therefore will be running faster than the requested or programmed speed.
This message is normal when using the Aux4 Spindle Jog function in high gear, because the 15-RPM spindle jog speed is below the slowest usable speed in high gear.
The PLC program requested display of a message on the screen, but the provided message code was not valid.
This indicates an error in the PLC program. Report the message to your dealer, along with the value in PLC variable W16.

PLC W16: stores the invalid message code
The program attemped to run an M3 or M4 spindle-start code, but the control is still in Manual Spindle mode.
Press the SPIN AUTO/MAN key in the top row of the operator panel to select Auto Spindle mode (LED on); then press CYCLE START to resume program operation.
The program attempted to run an M7 or M8 coolant-on code, but the control is still in Manual Coolant mode.
Press the Coolant AUTO/MAN key at the left side of the coolant controls row of the operator panel to select Auto Coolant mode (LED on); then press CYCLE START to resume program operation.
If you want to run the program cycle without coolant, you can press CYCLE START to resume operation without restoring Auto Coolant mode.
