Hey everyone, I am trying print a piece that uses dual extrusion. I am having issues when the second extruder is scraping the bed plate when it tries to print and messes up what the first extruder has printed. I am not sure what is causing this. I have the Ulltimaker 3 ext. I have also attached the files I am trying to print/ Thanks, 2color_treefrog_small_solid.stlZachary Loso2color_treefrog_small_hollow.stl
