<p>In Cura Slicer, is it possible to change the direction that the filament is laid down when making the top layer?</p>

<p>For example, in the above picture the filiment is laid down at about 45 degrees to the X\Y axis. Can I make it 90 degrees?</p>

I have a (retired) client whose career spanned more years than I\'ve been alive. He traversed his development from manual machining through punched cards/paper tape and through CAD/CAM, but always created the g-code from the ground up.</p>\n<p>One could, for example, locate a CAM program with which one is comfortable and set about defining tool paths and related configurations. Fusion 360 may have a slicer feature in the non-free portion; I\'ve not pursued that aspect of the software.</p>\n<p>One could also examine the g-code generated for a specific layer and make appropriate adjustments to the direction of travel, extrusion commands, speed, etc.</p>\n<p>An <a href="https://www.instructables.com/Manual-Gcode-for-3d-Stamp-Create-Square/" rel="nofollow noreferrer">Instructable</a> exists which describes a method to create a hollow cube for 3D printing, but it\'s severely limited in scope, in my opinion. It has triggered another thought, to use the g-code generated for laser cutting/engraving as a foundation for the above noted manual creation.</p>\n<p>For example, a g-code based laser (i.e., GRBL) could be commanded to cut lines spaced apart by the filament width when placed by the printer, often 0.4 mm approximately. LightBurn software (multi-platform, 30-day free trial, supports GRBL) would allow you to experiment creating the initial code, which would then require manual editing for temperatures and extrusion rates.</p>\n<p>This would require substantial experimentation and substantial time and effort.</p>\n'}, {'answer_id': 18649, 'author': 'R..
