First Layer Zig-Zag Calibration

prusaprinters

<p>This is a simple zig-zag to allow a visual calibration of first layer. This has the same purpose of the V2_Calibration.gcode that comes with Prusa's. <a href="https://www.youtube.com/watch?v=q_LqgABOICQ">Check Prusa's Video</a>.</p> <p>This have more zig-zags to allow you to keep tuning until you are satisfied, and has a vertical path so you can visualize it better when you have only a frontal approach to the printer (like me).</p> <p>The model lines have 0.4mm width and 0.2mm height, so you may have to proper set the slicer to detect them correctly. I'm using Slic3rPE but I think other slicers can reproduce the settings.</p> <h3>Print instructions</h3><p>Some settings are there just for precaution but I suggest to keep them as described:</p> <p>Enable detect thin walls to avoid glitches.<br/> Use 0.2mm layer height for first and other layers, so it will slice ok.<br/> Check layer width, set all to 0.4mm.<br/> Set Vertical shells Perimeter to 1.<br/> Disable skirt, you will not need that.<br/> I suggest using lower speeds to print this file, as the intention is to look at it an judge if the layer is being correctly extruded.</p>
