D Run-Stop-Jog-Continue (RSJC) - This feature allows the operator to interrupt program execution, jog away
from the part to perform a desired task, and then return to the interruption point and resume program execution.
Once RSJC is initiated, the operator is able to stop and start the spindle, jog the XYZ axes individually (axes
other than X, Y, and Z cannot be jogged), or command a tool release. The following describes the RSJC
procedure. (Any Mill Control ver. 11.10 and above.)
1) While a program is running, press FEED HOLD . This will stop all motion (after any canned cycle in
process has been completed.)
2) Press X , Y or Z followed by the HANDLE JOG key. The control will store the current X, Y or Z position.
Axes other than X, Y, and Z cannot be jogged.
3) At this point, the control will display the message JOG AWAY, and will tick once each second or so. The
operator can use the jog handle, remote jog handle, the HANDLE JOG increment buttons (.0001/.1, .001/
1., .01/10., .1/100.) or the JOG LOCK buttons to move the tool away from the part. Now you can use the
COOLNT key to cycle the coolant, and CW, CCW, STOP to operate the spindle. You can also use the
TOOL RELEASE button, and turn Through-Spindle Coolant (TSC) on and off using the AUX CLNT key. Note
that using AUX CLNT requires that the spindle be rotating and that the door be closed. At this point tools
can be swapped out and the associated length and diameter offsets adjusted. However, when the program
is continued, the old offsets will still be used for the return position and any motion commands already in
the queue. It is therefore unsafe to swap out tools and adjust offsets when the program is interrupted during
a cut.
4) When you’re ready to continue, jog to a position as close as possible to the stored position, or to a point
where there will be an unobstructed rapid path back to the stored position.
5) Return to the previous mode by pressing MEM , MDI or DNC . The control will only continue normally if the
mode that was in effect at the time of the interrupt is re-entered.
6) Press CYCLE START . The control will display the message JOG RETURN and rapid X and Y at 5% to the
position where FEED HOLD was pressed; then it will do the same for Z. The rapid rate override keys have
no effect during JOG RETURN. Note that the control will not follow the path the operator used to jog away.
Instead, it will perform simple moves without regard for obstacles. Therefore, crash is possible. If FEED
HOLD is pressed during this motion, the control will go into a feed hold state and display the message
JOG RETURN HOLD. Pressing CYCLE START will cause the control to resume the JOG RETURN motion.
When the motion is completed, the control will again go into a feed hold state.

D Program Review - In the PRGRM display, Program Review allows you to cursor through and review the active
program on the right side of the display screen, while also viewing the same program as it’s running on the left
side of the screen. To bring up Program Review, press F4 while running a program in MEM mode and PRGRM
display.
D Background Edit - This feature allows you to edit a program in MEM mode and PRGRM display while a
program is running. Type in the program number you want to edit ( Onnnnn ) and press F4 . You can then do
simple edits ( INSERT , ALTER , DELETE and UNDO ) either to an existing program, a new program or even the
program that is presently running. However, edits to the program that is running will not take effect until that
program cycle ends with an M30 or RESET .
D Tool Change Command - It is not necessary to turn off the coolant, stop the spindle, or move the Z axis
prior to a tool change (M06). The control will do this for you. Though you may choose to do these commands
sooner then when they actually happen with an M06.
