| GrinderODIDKaydonScreenV01 CheckWheelDiameterMargin | ( | ) |
Check whether the grinding wheel has sufficient diameter to complete the next dressing cycle.
Reads the current wheel diameter (#500) and minimum wheel diameter (#503) from pound variables and calculates the total material that will be removed from the wheel during the next cycle. For a Clean Dress cycle (#720 == 1500), it uses the clean dress loops (#680) and amount (#650). For all other cycles, it sums enabled dress cycles (Rough, Micro, Finish) using their respective enabled flags (#604-#606), loop counts (#681-#683), and amounts (#651-#653). If the remaining diameter margin is insufficient, a system global warning message is created with detailed wheel information.

| GrinderODIDKaydonScreenV01 InitialTouchOffCalibrationBtn | ( | ctrl_name | , |
| event_source | , | ||
| AxisID | , | ||
| ... ) |
Calculate and apply tool offset calibration from a touch-off position and measured part dimension.
Performs tool offset calibration for either the X or Z axis based on a physical touch-off procedure. The operator touches the tool to the part, records the machine position via InitialTouchOffTeach(), then enters the measured part dimension. This function computes the new tool offset using the recorded machine position, work offset, tool slide direction, wear offset, and measured value.
For X axis: Reads MachinePosX from XTouchOffDRO, measured value from MeasuredXDRO. Applies diameter-mode halving and tool slide direction correction. Formula: NewOffset = (MachinePosX - WorkOffset) - (XMeasureValue * Direction) + (WearOffset/2 * -1)
For Z axis: Reads MachinePosZ from ZTouchOffDRO, measured value from MeasuredZDRO. Formula: NewOffset = (MachinePosZ - WorkOffset) - ZMeasureValue
After setting the offset, both touch-off and measured DROs are cleared, a tool activation MDI command (TxxYY) is issued, and the tool file is saved.
| ctrl_name | (string) The name of the control that triggered this function (unused internally) |
| event_source | (any) The event source object (unused internally) |

| GrinderODIDKaydonScreenV01 JobSave | ( | ) |
Save the current job file to its existing path.
Entry point that wraps _JobSave() in a protected call via w.pcall(). If the internal function raises an error, displays an alarm message via w.AlarmMessage(). On success, logs the operator action and delegates to the job object's Save() method to write job data to the current file path.
| GrinderODIDKaydonScreenV01 JobSaveAs | ( | ) |
Open a file dialog to save the current job under a new name.
Entry point that wraps _JobSaveAs() in a protected call via w.pcall(). If the internal function raises an error, displays an alarm message via w.AlarmMessage(). On success, logs operator activity and delegates to the job object's SaveAs() method to prompt for a new file name and save the job data.
| GrinderODIDKaydonScreenV01 LoadJob | ( | ) |
Load the last used job file from the MachMotion profile.
Entry point that wraps _LoadJob() in a protected call via w.pcall(). If the internal function raises an error, displays an alarm message via w.AlarmMessage(). Reads the "LastJobName" string from the MachMotion profile. If the value is non-empty, loads the job file via the CurrentJob object's Load() method. This is called automatically during MachineScreenLoadScript() to restore the previously active job on screen startup.
| GrinderODIDKaydonScreenV01 MachineCycleStartFinal | ( | ) |
Perform final pre-cycle-start checks before allowing the grinding cycle to run.
Validates that the grinding wheel has sufficient diameter remaining to complete the next cycle by calling CheckWheelDiameterMargin().

| GrinderODIDKaydonScreenV01 UpdateEndOfProgram | ( | ) |
Detect and process the end-of-program event to record cycle time and reset the register.
Reads the EndOfProgram OEM register. When it equals 1, indicating the program has completed, this function reads the current run time via mc.mcCntlGetRunTime(), resets the EndOfProgram register to 0, saves the cycle time to the MachMotion profile under "LastProgramCycleTime", and sets the CycleProgressBarGauge to 100%.
| GrinderODIDKaydonScreenV01 UpdateGrindDROs | ( | ) |
Update the grinding DRO displays and calculate the rough grind amount.
Reads enabled state and amount for each grind stage from pound variables to compute the total stock removal and the micro+finish combined amount. The rough grind amount (#630) is automatically calculated as: StartDiameter - MicroAmount - FinishAmount - FinishDiameter - FinishStockAllowance. Updates the TotalStockDRO display and applies color coding to indicate invalid configurations:
| GrinderODIDKaydonScreenV01 UpdateGrindingCycleState | ( | ) |
Update the grinding cycle state LEDs and label based on pound variable #700.
Reads the current grind state from pound variable #700 and compares it to the previous state (LAST_STATE). Only when the state changes does the function update the UI, turning on the LED for the new state and turning off the LED for the previous state, and updating the CurrentStateLabel text. Recognized states are: IDLE(0), ROUGH_DRESS(1), ROUGH_GRIND(2), MICRO_DRESS(3), MICRO_GRIND(4), FINISH_DRESS(5), FINISH_GRIND(6), RETRACT(7), and CLEAN_DRESS(8).

Update the sparkout time gauge display based on the current dwell state.
Checks if the machine dwell signal (mc.OSIG_DWELL) is active. If dwelling, reads the remaining dwell time and the target dwell time via m.GetRemainingDwellTime() and m.GetTargetDwellTime(). Updates the SparkoutTimeGauge max value when the dwell target is greater than zero, and updates the current value when dwell target exceeds remaining time. If not dwelling, resets the SparkoutTimeGauge value to 0.0000.
| GrinderODIDKaydonScreenV01 UpdateWheelHeadRange | ( | ) |
Read the current wheel head range and persist it to the OEM parameter for the active wheel head.
Reads the wheel head range from pound variable #738, then reads the current wheel head number from the WheelHeadCurrentNumber OEM parameter. Writes the range value to the OEM parameter named "WheelHeadCurrentRange_N" where N is the current wheel head number. This persists the range selection across sessions.
| GrinderODIDKaydonScreenV01 UpdateWheelHeadRangeButtons | ( | ) |
Update the wheel head range button colors based on the current range pound variable (#738).
Reads pound variable #738 to determine the active wheel head range. If Range equals 0, sets LowRangeBtn to BTN_COLOR_ON and HighRangeBtn to BTN_COLOR_OFF. If Range equals 1, sets LowRangeBtn to BTN_COLOR_OFF and HighRangeBtn to BTN_COLOR_ON. For any other value, sets both buttons to BTN_COLOR_OFF.

Determines the target surface feet per minute (SFM) based on the current grind state: during dressing cycles (states 5-7), reads SFM from pound variable #541; otherwise reads from pound variable #731. Clamps the SFM to the MaxSFM limit from pound variable #737. Converts SFM to RPM using the current tool's wheel diameter: RPM = SFM * (12/pi) / Diameter. Further clamps the result to the maximum RPM for the current wheel head range obtained from GetWheelHeadCurrentRangeMaxRPM(). If the resulting RPM is greater than zero, writes it to pound variable #540 (CommandedRPM).
| GrinderODIDKaydonScreenV01 UpdateWorkHeadSpeeds | ( | WorkHeadSFM | ) |
Calculate and apply the commanded work head RPM based on surface feet per minute.
Converts the provided surface feet per minute (SFM) value to RPM using the current workpiece diameter from pound variable #616 via: RPM = |SFM * (12/pi) / Diameter|. Clamps the result to the spindle's current range min/max RPM limits obtained from mc.mcSpindleGetMinRPM() and mc.mcSpindleGetMaxRPM(). Only updates the spindle commanded RPM via mc.mcSpindleSetCommandRPM() if the new value differs from the current commanded RPM.
| WorkHeadSFM | (number) The desired work head surface speed in surface feet per minute |
| GrinderODIDKaydonScreenV01 UpdateXWearOffset | ( | ) |
Recalculate and apply the X axis wear offset and dress position based on current wheel geometry.
Reads the current tool's wheel diameter, the dresser roll diameter (#542), and the XDresserOffset from the tool table. Determines the dresser direction from the RotaryDresserDirection OEM parameter (Positive=1, otherwise=-1). Computes: XWearOffset = ((|XDresserOffset|*2) - |WheelDiameter| - |DresserRollDiameter|) * Direction X1DressPosition = (|XDresserOffset| - |WheelDiameter/2| - |DresserRollDiameter/2|) * Direction Writes X1DressPosition to the tool table and to pound variable #518. Updates the tool's X wear offset (MTOOL_LATHE_X_W) with XWearOffset and saves the tool file.
