Hi Robert,
i talked to GP protoCNC. He told me that you can contact him after 10th of september, because he is on holiday now. He'll give you the last version of the Screenset that works with UCCNC ver.1.2111. The macros for manual tool change and automatic tool chage are generic. To change the tool manually like you want, you can modify the M6 macro using the code of macro M20101 with some modifications. If you have some problems to modify the macros just send me a PM. I hope i was helpful.
