EstlCAM suddenly processing differently

Mini Rambo build sourced from the site.
EstlCAM set up identical to instructions.
Have done about 100 cuts without issue.
Same SD card (but also ran the codes through USB and got the same issue)
Inkscape->EstlCAM
Machine has been cutting codes like the first example perfectly.

All of a sudden its creating code like the second example and the machine rapids to place then seems to stop moving or is just moving so slow I can’t tell. Motor just clicks. When I abort the print it takes about 30 seconds for the motor to quiet.

Machine jogs around table without problem.

Thanks for any help.
