Subject: Update on CNC Machining Problem

Hi Ben,

1. Thanks for getting back to me so quick on the CNC spindle configuration problem. 2. I'm writing to ask about the analysis we did yesterday. 3. Sorry about the bottleneck last week with the faulty G-Code; it looks like we fixed the version conflict.

We need the client to provide the new tolerance documentation before we can fully release the latest production batch. 4. Can you tell me when the client will send the final confirmation?

5. Talk soon.

Best, Anna
