For our January Spikemark tip, we’re going to discuss a common situation when writing cues: You want two cues to be linked, but you need a delay between the completion of the parent cue and the start of the child cue. For instance, you need a prop wagon to travel onstage, wait 15 seconds and then travel offstage. Your first instinct might be to write a Time Link to Cue #1 with a delay of 15 seconds, but Time Links are triggered from the start of the cue, not the completion. With a simple Time Link between two cues the wagon would move offstage 15 seconds after it started moving onstage regardless of how long the onstage move takes. The solution is to write a dummy cue. Say you have Cue 1 that moves your wagon onstage and Cue 2 that moves your wagon offstage and you need a 15 second delay before the wagon tracks offstage. Insert an intermediate cue 1.5, and give the motor in this cue the same target as the completion target of Cue 1. When Cue 1 completes, Cue 1.5 will start and stop immediately, since it’s already at it’s target. Now make Cue 2 a Time Link off of Cue 1.5 with a delay of 15 seconds. The delay will start with the start of Cue 1.5, which is the same as the completion of Cue 1. Now you’re all set. That’s it for this month. If there’s something you want to know how to do, or if you’ve figured out a trick of your own that you’d like to share, please let me know in the comments or email me at email@example.com.
Last week we finalized the process for ETL certification and soon our control equipment will carry official ETL labels. ETL is a nationally recognized testing lab, much like UL, and their listing is proof of product compliance to North American safety standards. By having ETL certification, CCI is now authorized to make listed industrial control panels, which is helpful when the equipment is being inspected by local electrical inspectors. As an interesting side note, we did not have to make any electrical changes to any of our products to pass the inspection, which is a nice validation of the high quality work we do here.
