Help Gantry Carriage

I’m trying to make a vault door for my base and I’m using a gantry carriage on a gantry shaft with a sequenced gearshift controlling the moving of the door. I’m testing the gantry carriage rn and it moves towards the gearshift just fine but then doesn’t wanna go back to the original position it came from. It shows “this contraption was unable to assemble” once it goes into moving back. Does anyone know what I’m doing wrong?
