The bridge motion was slowed due to encoder homing issue. It is likely that the problem which occurred yesterday caused an velocity fault (mismatch between encoder speed and commanded speed), which unlatches the homing status for the bridge motion axis.

When the bridge was in the southmost position (bumper pressed against wall), the position readback was: 0.353 m, encoder count = 5164003.

The bridge was moved to the "zero position" as indicated on the remote display - the tick was aligned with the zero.

The encoder was homed at this position. The home position readback was: 0.356 m, encoder count = 5164447. Note that this position is in alignment with the measuring tape zero mark, not pressed up against the wall.

The bridge was run to its full extreme positions in either direction to confirm proper slowdown and stopping behaviour. It appears to be functioning normally again.
