My FFCX loses/gains a bit on rounds and diagonals. Still looking into why. Follow the saga here

You might put the file out here so we can try it.

Getting ready to start printing to see what happens. It says about 2 hours.

So far you can see that the postg hole are poor. It is like it is trying to print in air. The first layer is ok but then these do not print correctly. I did see the file has issues but I am going to let it run as is to see what happens. Then I will run fixes on it a nd see how it goes.
The pic is rotated and for the life of me I can not get it to post correctly.

It printed ok. I think there are some problems and running through a fixer could help. This was printed with basic default settings and fairly fast at 3600mm/min and the filament is generic PLA nothing special.

Thank you, Idk how but I must have unsubscribed myself from my thread somehow, stopped getting notifications. I appreciate you doing this, thank you!

Yea, Flashforge sent me a new z motor and threaded rod. I installed it and still have the issues, so its not the z motor or rod.

I actually just picked up another printer and the prints are coming out great, so definitely a problem with this particular printer. Here you can see photos of the lid with its oozesheild for both my problem printer and my new one.

Now a little more than a week later and the new printer prints are starting to look like this... Since it has no gradually happened to 2 printers, I'm wondering if since the parts are thin walled/smart parts, if the rapid movements are loosening something or making it skip over time? Yo can still see the lines from when the printer was brand new a week ago, they just weren't as protruding and noticeable.

Can't see pics right now, security locks them out but I can look later to see what you mean.
