I don't think that changing a screenset will change other aspects of that profile. The macros are stored per-profile, i.e. typically per machine, so if you updated a macro in one profile, that change won't be seen in other profiles.

However, there are a few odd things that can happen around M6 that aren't quite right if you are using a CSMIO-IP/M, and I wouldn't be surprised if it's not true for other CSMIO variants. For example, when I first started playing with tool height setting/resetting during an M6 tool change (i.e. between the calls to M6start and M6end), there were problems about losing X and Y position. The fix (in my case) was to "upgrade" to an earlier version of mach3. I'm currently using 3.043.028 which is not the latest version but can still be downloaded and installed. Remember to save any profile modifications in a custom machine profile and not mach3mill or any of the other out-of-the-box profiles or they will definitely be overwritten. The CSMIO compatibility thing is well-known and documented but you won't generally find it unless you go looking for it.
