Manual program

Hi everyone,

Yesterday I carried out a manual program on a part and run the batch complete and unset the fixture. This morning I was given another batch to complete so I set my fixture back up, inserted the part onto the fixture and did my manual points for the alignment. However, there seems to be an issue with the 'Z' movements, they seem to be completely different to how they was yesterday. The probe now stops above the job and misses the part. I have used the same alignment as yesterday. Would anyone happen to know what I could be doing wrong?

Thanks in advance,
Mitch
