Will try to keep this short. I notice Mbot worked with Simply3D to get an Mbot3D machine profile into it. These programs, like ReplicatorG and Repetier are just the graphical host package for the slicers. However, they have to have a compatible machine profile to provide the compatible G-code. Repetier-Host, on their website, has provisions for working with a manufacturer to have a complete install package with profile compatibility. There is something about the USB interface with the Mbot that won't complete the com link with Repetier. ReplicatorG looks dead since Makerbot got bought out by Stratasys. By supporting Repetier-Host with a Mbot machine profile, the problem of ReplictorG being outdated and close to creaking old age is solved.
