Alternative controller?

Hi - I have a Longmill mk2 and consistently have problems with gsender. All of the 1.4.x releases have had showstopper issues for me (OSX) and performance with complex paths on earlier versions makes jogging impossible unless I unload the models. Many of these issues have been reported here (and I have logged bugs on GitHub). So I am considering alternative approaches.

Does anyone use a different software package or a different controller like a Masso G3 or Acorn? This seems relevant as well for AltMill in the future, which seems to be leveraging gsender.
