I recently got a neptune 4 max and it wasn't able to print a clean benchy, no matter what i tried i keep getting some sort of z-wobble but only on the x axis (extruder moving left and right)
The red/green benchy was my first benchy for which i used the g-code provided with the printer. The yellow ones i sliced the benchy myself in the elegoo cura slicer with basic settings
