Hi Kerryw, Being that Mattercontrol 2.0 is a slicer it's self, I am not sure what you mean by switching slicers. You can always slice a file in another slicer and import the G-Code into Mattercontrol to run your printer if you like. Upon further discussion with some of my colleges here, MC 2.0 dropped the option for different slicers, it was supported in previous versions but for the time being we will not have it in 2.0. Lets chalk my previous statement up to lack of knowledge of the previous versions!
