<p>I am slicing with Cura and Slic3r and one important thing that I recently took my attention is that cura positions head in start point of the new layer and then lifts the nozzle. That caused my few printouts to fall as they collided with the nozzle. </p>

<p>Slic3r behavior is different: it raises the nozzle in last printed point and then moves to a new layer starting point (which for me is more obvious)</p>

<p><strong>Is there a way to instruct Cura to lift nozzle before it goes to the starting point of a new layer?</strong> excluding Z-hops.</p>

When the next layer starts the extruder goes to the layer start from a 2 mm rise.</li>\n<li>Write a plugin for Cura to post-process (<code>C:\\Program Files\\Ultimaker Cura x.x\\plugins\\PostProcessingPlugin\\scripts</code>) the G-code file to inject the code to Z hop before the start of every layer, or a plugin that adds a new option and/or category to the slicer settings sidebar of the GUI.</li>\n</ol>\n"}, {'answer_id': 6346, 'author': 'profesor79', 'author_id': 9730, 'author_profile': 'https://3dprinting.stackexchange.com/users/9730', 'pm_score': -1, 'selected': True, 'text': '<p>OK, after going via all the options I found that CURA has a combing mode which reduces retraction and offers another option which is <code>Avoid Printed Parts When Traveling</code>.</p>\n\n<p>That solves my problem.</p>\n'}]
