Thanks for the info, I will check tolerances and the quadaling option. As an update I ran this past week and machine was arround 5% for a very small lot size, for a larger size lot it was less than 2%, Now I know it still higher than our newest machine (assembleon ~0.3%) the expectation is to bring the old quads to such level.
