For all those having trouble with the KoP stop button, it is possible to run in the pits without it. On the driver station navigate to the tab called diagnostics, and a list of items plugged in should appear with red and green gots beside them. double click on the (presumably) red dot next to the "Stop Button" label and choose the option "Yes, I'll be careful". A dialog box will then coundown 20 seconds and then the robot should be enableable without a stop button plugged in. We had our button die on us as well in the pits after travel, but due to errors in packing had not the solder materials needed to fix it
we'll learn for LA regional I guess.
