Exactly, I got a reply to a noob question from Black5f (Tom) that was so detailed that I felt guilty when thinking about the time he had spent putting it all together, and I daren't even think about whether the excel sheet (available for download ) was created just for me.
If I can return this kind of support to fellow strivers, in questions about electronics or programming G code in Visual Basic I will be very glad.
It's nice to have contact with Brits again after leaving the UK over 30 years ago and now living in Germany.
