First layer already has weird zigzags

[docwilco]

I'm not sure what the best way to report these is, but I made a body that has what should be very close to straight lines, but after an AW pass, the printer makes very weird zigzags on the first layer. I use AW straight from Cura, so not sure what to provide other than the 2 GCode files, which I have attached.

I didn't print past the first layer, because I didn't want to waste filament.

FYI, all my other prints with AW enabled have been going just fine! This was the only print so far that this happened with.
