Thanks for the g-code files. Looking at them I can see that they contain z-hop moves with a silly feedrate (F17987547480000). This is a recently introduced regression (see https://github.com/Ultimaker/Cura/commit/ce9f3c9bcc79fdd596bd3c5ac87ce9ba7120a031).   You can work around this by either setting the Maximum Speed Z in the printer definition or by setting or the Maximum Z Speed value in the profile.
