G1 Z0.795 X123.865 Y117.595 E0.07735 G1 Z0.799 X122.929 Y118.797 E0.08322 G1 Z0.802 X122.007 Y119.869 E0.07728 G1 Z0.805 X121.032 Y120.899 E0.07746 G1 Z0.807 X120.211 Y121.684 E0.06204 M106 S255 G1 Z0.6 F9000.000 G1 X120.211 Y121.684 F9000.000 G1 Z0.601 X119.959 Y121.926 E0.01911 F600.000 G1 Z0.604 X118.862 Y122.877 E0.07932 G1 Z0.607 X117.719 Y123.772 E0.07930 G1 Z0.611 X116.492 Y124.640 E0.08216 G1 Z0.614 X115.309 Y125.392 E0.07657What happens is that the first two layers print fine (these are full bottom layers), then the spiral print starts at 0.4mm height, and in the first full circle travels up to 0.8mm (the above gcode shows the end of this). Then it drops down 0.2mm to Z0.6mm, before doing the next spiral up to 1mm! The rather odd movement going upwards isn't ideal (squashing the previous layer), but the drop in Z at the end of each layer causes a seam, which rather negates the point of doing a vase print... It's like it's trying to do a normal print AND a spiral print.

This is WITH relative extrusion (you can tell from the small values of E):
G1 Z1.680 X116.399 Y75.358 E0.08680 G1 Z1.683 X117.526 Y76.147 E0.08658 G1 Z1.687 X118.830 Y77.162 E0.10407 G1 Z1.690 X119.925 Y78.112 E0.09121 G1 Z1.690 X120.155 Y78.332 E0.02006 G1 Z1.5 F9000.000 G1 X120.155 Y78.332 F9000.000 G1 Z1.502 X121.049 Y79.189 E0.07793 F1800.000 G1 Z1.505 X121.969 Y80.163 E0.08435 G1 Z1.508 X122.940 Y81.295 E0.09392 G1 Z1.511 X123.868 Y82.494 E0.09545 G1 Z1.514 X124.635 Y83.590 E0.08417Same problem as before; in one revolution, rather than going up the layer height of 0.2mm, it goes up nearly 0.4mm, then drops down to the correct layer height.
