Gaps in the infill in Cura + plugins Posted July 30, 2016 · Edited July 30, 2016 by Guest Thanks! I'll try that next print. Ultimaker + Cura. I don't think it gets any easier than this. I've tried using a Leapfrog and its slicing software, and it takes FOREVER, if it finishes at all! The printer, however, seems reliable enough. One day I'll try to figure out how to get Cura to talk to it.
