I, too, have grown accustom to using Repetier-Host. Recent improvements in 3D Printer software have made possible the use of G2's and G3's ( Arc Movements ). Similarly, I currently go back and forth using the Cura-Engine plugin, and/or, external from Repetier-Host, slicing my parts using Ultimaker Cura, (now at version 5.3.1 ) for which there is a plugin, ArcWelder. ArcWelder actually joins the itty-bitty, teentsey, weentsey, segments of circles or radii into a smooth hole or curve. In my use, it cuts my file size to almost half, and cuts down print time a bunch. ANYWAY..... I didn't come here to advertise. I am looking for a way to integrate Ultimaker Cura as a plugin. So, I am struggling with making " Add Slicer " in the Slicer Manager. So far, all that I can do is add the name I want. Has anyone had any success with this endeavor?
