It's good you were able to access the secret screen. Counter overflow I think relates to the machine having lost it's machine origin position data. Do you have a printer in the machine to print the machine data? This is very long time ago for me, an

Had cheacked the archives but I didn't see much about their comparison: 1. Throughput 2. Rework Rate 3. Effect on Placement Accuracy 4. Cost (cheaper or more expensive in the long term?) Has anyone compared the above. Please help me.

Fraser: You're correct!!! We did our analysis on paste rather than glue and I missed that when changed things to respond.
