@GregValiant G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up G92 E0 G92 E0 G1 F1800 E-5 <----Here. ;LAYER_COUNT:171 ;LAYER:0 M107 G1 F300 Z0.4 <---- picks up nozzle? In the previous code snippets, it is there too. The amount varies I think based on the retraction settings you have stored. Update: So I made a noob mistake (yes, I've only had the printer a short while). It was the z-offset that was really causing the problem for my first layer. However, the above extrusion is still interesting, although not critical anymore.

Having the same issue here. I have downloaded the printer settings plugin, and in "settings" can see the "Nozzle Switch Retraction Distance" setting (with the checkbox). When hovered over it, it says that its not visible because the printer only has one extruder. In the printer settings, printhead settings, number of extruders, it will not allow me to select more than 1 extruder (I have the Creality Ender-5). So I cannot adjust that setting. I have verified however, that the extra line of code is in the gcode, compiled during slicing, and is after the end of the start gcode. Need help with this, as it is causing skirt to mess up, and resulting in failing 1st layer prints.
