I had an occasion to drill numerous holes. I needed three different sizes of holes. The holes drilled are uniform in size but are larger than designed. They are round so I believe the X and Y axis movements are performing as designed. I went back to designer and double checked the size I wanted and they are correct in designer. They are as follows:

Designed - .250" Actual Size - .312"
Designed - .400" Actual Size - .470"
Designed - .500" Actual Size - .560"

I am talking about 100 of each size holes called for all being perfectly the same oversize measurement. I would think if was mechanical the hole size would vary or they would be oblong.

I am using Version 3.106, Build 38.

Any Suggestions?
