PathPilot Interface
• Cycle Start is pressed when no G-code program is loaded
• Cycle Start is pressed before the mill has been referenced
Single Block – Turns Single Block on (LED illuminated) or o. When Single Block mode is acve, the
mill executes one block of G-code, then pauses and ashes the Cycle Start buon LED on and o,
inving the operator to press the Cycle Start buon to execute the next line of G-code. This feature
may be turned on or o before running a program or during program execuon.
NOTE: Non-moon lines are ignored by Single Block mode. This means that the PathPilot interface will skip
comment lines and blank lines.
M01 Break – Turns M01 Break buon on (LED illuminated) or o (LED o). When M01 Break is
acve, and an M01 (oponal stop) is programmed in the G-code le, the mill stops when it reaches
the M01 line and the Cycle Start buon LED ashes on and o. The mill connues to execute the
program lines aer the M01 when the Cycle Start buon is pressed. This feature may be turned on
or o before running a program or during program execuon.
Feedhold – Turns Feedhold buon on (LED illuminated). Turning Feedhold on pauses mill moon,
and the Cycle Start buon LED ashes on and o. Turning Feedhold on leaves the spindle running (if
it is already on). To turn Feedhold o, click the Cycle Start buon. The Feedhold buon works during
program execuon or during manual data input (MDI) moves (G-code commands entered into the
MDI line below the G-code lisng on the Main screen). Feedhold has no eect when the mill is not
moving. Also, applicaon of Feedhold is delayed if clicked during a spindle-synchronized move (e.g.,
G84 tapping cycles) unl that spindle-synchronized move is complete. The feedhold funcon is also
connected to the keyboard’s space bar – pressing the spacebar on the keyboard is equivalent to
clicking this buon with the mouse.
Stop – Stops all mill moon, including spindle moon. If clicked while running a program or during
an MDI move, the Stop buon stops the mill and rewinds the G-code program. Stop doesn’t change
the current modal state of the mill (G54, G01, etc.).
Coolant – Turns coolant on (LED illuminated) or o (LED o). Clicking this buon turns power on or
o to the coolant accessory port on the side of the electrical cabinet – so long as the Coolant switch
on the operator panel is in Auto mode. This buon is the equivalent to M8/M9 G-code commands.
It may be clicked before, aer, or during program execuon, or an MDI move.
Reset – Brings the mill out of an E-stop condion, resets G-code modalies, clears alarm messages,
and rewinds the G-code program. When the mill is rst powered on, or aer an emergency stop
(E-stop), the Reset buon ashes back and forth between red and white. When this buon is
ashing (aer power has been restored to the mill), clicking the Reset buon starts and veries
communicaon between the mill and the controller. Reset may be clicked any me aer the mill is
powered on. Reset does the following:
• Resets all modal G-codes to their normal state including work oset to G54 default
• Rewinds a G-code program
• Stops a program, MDI move, or homing move if one is currently in progress
