JOG(OPCS) Optical Printer Control System JOG(OPCS)
NAME
jog - jog motors interactively
USAGE
jog # jog any channels
jog [channels] # jog only specific channels
EXAMPLES
jog f # jog the 'f' channel with the numeric keypad
jog # jog ANY channels with numeric keypad
DESCRIPTION
This command brings up a menu oriented display where single key
presses can run the printer. Like the KEY command, the function
keys along the top of the keyboard allow the operator to run frames
on the projectors or the camera.
In addition, keys on the numeric keypad (as shown in the on-screen
menu) are active for jogging the motors.
You can define the number of pulses that VERNIER and CRAWL move per
keypress. See JOGSTEP(OPCSDEFS).
1 Reverse in vernier mode. Hold to repeat.
2 Reverse in crawl mode. Hold to repeat.
3 Reverse in slew mode. Runs until key is released.
4 unused
5 unused
6 unused
7 Forward in vernier mode. Hold to repeat.
8 Forward in crawl mode. Hold to repeat.
9 Forward in slew mode. Runs until key is released.
+ Select next channel to jog (ie. 'a' becomes 'b')
- Select next channel in reverse (ie. 'b' becomes 'a')
ALT-A Selects the 'a' channel
ALT-B Selects the 'b' channel, etc..
V Toggles the 'Slave / No Slave' mode. If slaving is
off, you can jog the zoom without moving the focus.
With slaving on, moving the zoom will also move
the focus.
Z Sends current channel to '0' position
R Allows the operator to reset counters using the
UP/DOWN arrow keys, and by typing in numbers.
ESC or Q returns to normal JOG editing.
U Unlocks the motors for free-wheeling (if the option is
installed on your system).
ENTER Appends the current positions of all motors as a
'keyframe' position to the keyframe list.
L Load keyframe positions. Loads them so they can be
added to, edited, etc.
E Edit the keyframe list. See below 'KEYFRAME EDITOR'
S Saves keyframes compiled with the ENTER key, and in
the E)ditor. See below 'KEYFRAME EDITOR'.
C Clears all keyframes so you can start again.
NOTES
If you are jogging positioning motors (not frame counter motors),
and find that releasing the key does not immediatly stop the motor,
check the PPR(OPCSDEFS) setting for that channel. Normally
positioning channels should have a low value like 10 for PPR.
When jogging the ZOOM, follow focus is not immediate when slewing.
During a move, only the zoom will move until the key is released.
At that point the focus will move to the appropriate focus position.
This 'delay' is noticable with especially with the SLEW keys (3&9).
GOTCHYAS
When using JOG(OPCS) inching keys on a channels like the camera and
projector, the counters WILL NOT CHANGE, so as not to loose your frame
counts for that channel.
BUGS
Currently the 0-9 keys (non-numeric keypad number keys) are not active
during 'jog', although in the future they will echo the same functions
the KEY command currently has.
THE KEYFRAME EDITOR
-------------------
The keyframe editor is a simple tool to help correct mistakes made
while finding keyframes. It is a sub-menu of the JOG command, and
is accessed as 'E' from the JOG menu.
UP/DOWN Move the cursor to different keyframes. In the
keyframe editor, the position list at the bottom
right of the screen shows the positions FOR THE
KEYFRAME the cursor is currently on.
PgUp/PgDn If you have many keyframes saved, this will
scroll through them a page at a time.
DELETE Deletes the keyframe positions the cursor is currently
sitting on, and all positions below it are
'moved up one' to replace the deleted keyframe.
INSERT This inserts the current motor positions as a new
keyframe where the cursor is sitting, and all the
other key positions below it will be shifted down one.
G Sends all motors to selected keyframe's positions.
ESC Returns to the JOG mode.
COMMON KEYFRAME EDITING
-----------------------
DELETING ACCIDENTALLY SAVED KEYFRAME POSITIONS
----------------------------------------------
If you save the same keyframe twice, you can correct the problem
by entering the editor, find the extra position with the UP/DOWN
cursor keys, and hit the DELETE key on the extra keyframe. Hit ESC
to continue finding newer positions.
REPLACING BAD KEYFRAME POSITIONS WITH NEWER ONES
------------------------------------------------
Assuming you saved a key position, and later want to replace it with
better positions you just found, enter the editor with the motors at
the newer positions. Find the old keyframe with the cursor and hit
the DELETE key to remove it. Now hit the INSERT key to insert the
current positions of the motors where the old positions were.
