PathPilot Interface
When the mill is at rest, these readouts are also operator entry elds. Change the current work
oset posion by clicking in the DRO eld, which illuminates. Type a number, for example 4.0, and
click Enter on keyboard. Press the Esc key to return to the original value.
This technique is used for seng any DRO. Remember to click Enter aer any DRO change. If you
forget and just click on another DRO, any value you have just entered is discarded. This is designed
to avoid accidental changes.
For convenience, the Zero buon to the le of the axis DROs can be used to set the current work
oset posion for that axis to 0.000.
DTG (Distance to Go) – Just to the right of the axis DROs are the DTG (see Figure 6.2) or Distance
to Go labels (light blue) that are read-only and display the distance remaining in any single move.
If you feedhold the mill in the middle of a move, or turn the Maxvel or Feedrate overrides to 0
percent, these labels display the distance le in the commanded move. These labels are useful
when proving out a part.
Ref Axes Buons – Ref X, Ref Y, Ref Z, and Ref A buons reference the axes to their home switch
locaons. This must be done aer power on and before running a part program or using MDI
commands. The axes may be referenced simultaneously, though it is common pracce to reference
the Z-axis rst to clear the spindle or tool from the area of the workpiece or vise. When referenced,
the LED is illuminated.
Status – The Status line displays the currently acve G-code modalies and the acve tool. A more
detailed descripon of these acve G-codes is provided on the Sengs tab.
Jog Acve LEDs – Between the (Zero) Axis and DROs are LEDs. If the mill is equipped with an oponal
Jog Shule (PN 30616), the acve jog axis is indicated by an illuminated LED (see Figure 6.3).
6.2.3 Manual Control Group
The Manual Control Group's buons, slider, and
DROs allow the operator to perform tasks related
to manual control of the mill, including jogging
the mill axes, changing the current tool number,
feed rate, or spindle speed, and starng or
stopping the spindle (see Figure 6.4).
