I like everything about it! The interface has so many options for customization to meet our needs as well as other user's requirements we can see in mattercontrol community forums or github repositories (if they don't have one). It works great with multiple computers at once which makes managing jobs easier than using some of those expensive third party programs out there such as Ultimaker Cura etc.. There aren’t any downsides from my point if view but maybe someone who knows more will be able tell me what their thoughts are regarding this program because i haven;' t used anything else since trying MC first time back when version 1 was released 5 years ago now :) We use CNC milling machines instead traditional manual labor processes thus reducing product lead times by several weeks up until months depending upon projects size compared against batch sizes produced manually via old fashioned methods - not.
