Help with issues i'm having with diode switching

[daryl]

Hope you don't mind me posting this like I have.

I'm having some issues with diode switching and just wanted to see if people with more knowledge than I could shed some light on it and also check that what i'm doing is ok.

Can you have a look at the latest post on this topic:
