Hi all,
im kinda noob but i noticed while printing bed level test squere that my nozzle moves like this- extrudes a line, stops extruding, moves back on top of the extruded line to the beginning and then goes and extrudes another line 🙄.
I allways thought that its should be Zig-zag- extrudes one line, and as the nozzle is coming back, extrudes antoher to the side of the first one. like in the pic.
Mine goes like this, as described before, sry for the awsome focusing skills my phone has.
So my question is, is this normal or i have thicked some box somewhere?
regards,

First off, the nozzle path is controlled by your slicer, the printer just moves the XYZ and Extruders and changes the temperatures however the slicer GCODE tells it to.
Secondly, from the video we can‘t see if it is laying down a line on the return path or not. Certainly is moving in the right direct. When it gets to the ”end“ of a line, it should move over with width, and extrude on the way back. From what we can see of the video, that is exactly what it is doing. If you have a magnifying glass or microscope, take a close up loop and see if you can tell. Or put a .8mm nozzle on and change your config and slicer settings to match the new size nozzle and see if it looks like the wiki picture (that looks like at least a 1mm nozzle if not bigger - and the slicer will work a little differently at the end of lines at that size i bet).
In other words I bet it is doing a zig zag, but you just can’t tell. See if you can get a different picture from a bit higher so if we can see it a bit better.

Update, swap my nozzle to 0.8 did couple of test runs, found cura settings- top/bottom pattern where u can swap between lines/zigzag/cocentric. And i guess i had a bit of a overextrusion problem that squeezed fila to the oncoming path, making it hard to see the zig zag motion.
case closed.
