The position of the infeed arm might have shifted, due to a crash or loose screws!
double check the correct position.
Therefore insert „0“ to the can height setting and press „GO“.
If you ever changed the overtravel setting in the tuning level, set this value to „1“.
Now measure the distance from the infeed arm to center of the welding roll.
The correct reading should be: 216 mm!
With this reading the canbody will have 1 mm overtravel.
