I've done 4 back to back free entry stamps after having had a Non-B for 3 years. I spoke Thai to the immigration officials at the booth and explained very clearly my intentions. Yes I am trying to enter on a free visa stamp, yes I live here and I am planning to get a proper visa to settle down again properly but needed some time to prepare the right visa type.
They did not object, and gave me the stamp without further questioning every single time. I am not planning to repeat the experience a fifth time though as I will be making my new non immigrant visa soon.
I guess the way you present yourself is also pretty important as, after all, no matter what the law says, they're the ones who decide whether or not to let you in.
