Has anyone had the fault 'Move Buffer Full' and how do you solve it.

Thank you Steve worked straight away

Hi everyone, I have a Novamill and the turret indexer is out of position. When I go to do a tool change the indexer is lining up half way between the tool positions. Does anyone have a solution to my problem. I know how to reference T1, move the indexer in, out and turn it cw & ccw in MDI. Thanks :d...
