F2 – Search Invoking this option will bring you to the “Search and Run” menu. This menu will allow
you to specify the program line, block number, or tool number at which execution of a program is
to begin. Program lines are numbered from the top of the file down with the first line numbered
1. To enter a block number, place an "N" in front of the number. To enter a tool number, place a
"T" in front of the number. Pressing CYCLE START from here would start the program at the
point you specified.
An extra option unique to the “Search and Run” screen is the F1 – Tool Change “Do Last Tool
Change” function. This key toggles the tool change option as shown on screen. A "YES" tells
the control to perform a tool change so that the tool specified for the line or block has the tool
indicated in the program. A "NO" uses the currently loaded tool, regardless of what tool is
specified for the line or block being searched.
NOTE: You cannot search into a subroutine.
F3 – Repeat On/Off This key toggles the repeat feature for part counting. When part counting is in
effect and Repeat is on, the job will be automatically run again until the specified number of parts
has been run. The On or Off label indicates the state to which the repeat feature will toggle to
when pressed. It does not indicate the current state. The current state is indicated in the user
window above.
The Part Count: prompt is used to set the Part count. Positive values set the part counter to count up and
negative values configure the part count to count down. For example, if 10 is entered in the Part Count
prompt, the Part Cnt in the status window changes to 10 and the Part # changes to 0 with an upward arrow
indicator. When a job is run and then completes, the Part # will increment to 1. If repeat is on, the job will
automatically start again and keep running until the Part # has reached the Part Cnt. If a –10 is entered in the
Part Count prompt, the Part Cnt in the status window changes to 10 and the Part # changes to 10 with a
downward arrow indicator. When a job is finished, the Part # will decremented to 9. If repeat is on, the job
will automatically start again and keep running until the Part # has reached 0.
F4 - /Skips On/Off This function toggles the block skip feature. When block skipping is on, G-code
lines that start with a forward slash character ‘/’ are skipped, i.e., they are not processed. Note
that because of the way a job is processed (in a pre-processed buffered fashion) the effect of this
key may be delayed if you press it while a job is running. The On or Off label indicates the state
to which the /Skips feature will toggle to when pressed. It does not indicate the current state. The
current state is indicated in the user window above.
F5 - Block Mode Turns single block mode on and off. This is similar to pressing AUTO/BLOCK. If
Single Block mode is on, the CNC software will stop after each block in your part program and
wait for you to press CYCLE START. Note that Auto mode is the default mode. If you use this
key to turn on Single Block mode and then run a job, Auto mode will be re-instated when the job
ends. The current state of this setting is indicated in the user window above.
F6 - Optional Stops Turns optional stops on and off. If optional stops are on, any M1 codes that
appear in your program will cause a wait for CYCLE START (just like M0). If optional stops
are off, M1 codes will be ignored. Note that the default mode for Optional Stops is off. If you use
this key to turn on Single Block mode and then run a job, Optional Stops will be set to off when
the job ends. The current state of this setting is indicated in the user window above.
