okay pet-g is NOT pla.

It needs to be printed slowly and fairly hot. You've got no chance at 75mm/s
Also looks like you're too low on temp.
Start at 30mm/s and maybe 240c. The print bed also needs to be pretty hot. Can't remember off hand, but 70-90c would seem reasonable.

It's also a bugger to get the retractions right as well.

Don't get me wrong once you find the magic settings for you machine, it's amazingly strong stuff. But easy to use - it is not.
