Thanks for the different information provided here.
I also possess a creator 3 and having trouble with simplifiy3D and dual color print in simplify.
It starts well, but at every tool change, I'm having an issue just before the back and forth wiping, we can here a noticable noise (like the Y axis "forcing" to the wiping), and it result on a layer shift at nearly every tool change.
I tried removing lines from the tool change script without success.
If anybody have any clue or idea of what's happening it would be really nice.
