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). Key Description --- --------------------------------------------------- 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 - 5 - 6 - 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 'Slave / No Slave' mode. [See COMMENTS] Z Sends current channel to '0' position R Reset counters [See COMMENTS] U Unlocks the motors (runs 'unlock' command) ENTER Saves current positions as a keyframe. L Load keyframe positions. [See COMMENTS] E Edit the keyframe list. See below 'KEYFRAME EDITOR' S Saves keyframes created with ENTER key, and E)ditor C Clears all keyframes so you can start again. COMMENTS V - If slaving is off, you can jog the zoom without moving the focus. With slaving on, moving zoom also moves focus. R - In 'reset' mode, use Up/Dn arrows to select the channel to reset, and enter the new numeric value. Use ESC or Q to return to normal jog mode. L - Loads the keyframe positions so they can be added to, edited, etc. 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.
