With their new MatterControl 1.5 update, MatterHackers has added a huge list of new features as well as several fixes to lingering bugs from the first release. The update includes an entirely rewritten support system to optimally place support structures. It also includes new features like “Baby Stepping” or position tuning, as well as improved 3D model joining or part merging, improved seam hiding and the ability to cancel a print while the printing is warming up.
