Here's something easy to help with that. Is your pnuematic code working? If yes, the CAN ID is set in LabVIEW to whatever you have it set on the PCM. The pistons wouldn't function without it.
For your other post, I want to be very precise about what you're saying. "We can push code" tells me you're NOT enabled. When you're pushing code, the robot is disabled.
You'll want to push code, connect to the robot, hit enable in the driver station. Once that's done (and the enable stays green rather than reverting to disabled), you have an enabled robot.
While the robot is in that enabled state, have you looked at the Phoenix Tuner? When you get that error, did you look back at the driver station to confirm it is still showing an enabled robot? If not, let's try to get to that state first. If so, you'll likely get better help engaging the CRTE folks. By virtue of the pistons moving, you've verified your wiring is good. You've verified your code is good. You're left working with the Phoenix Tuner and they're better experts than anyone on that tool.
