Z Resonance Issue
Hi, I am relatively new to 3d printing, but I have worked out that I have a Z Resonance issue.
Here is a picture of the issue

I have seen a few people say that removing the bearing on the top of the z axis threaded rod fixes the issue. This is great, however I am not sure how to remove it without damaging the printer beyond my fixing.
I would like to try to fix this myself before contacting flashforge directly.
Any help that this forum may provide would be greatly appreciated!

All flashforge printers, at least pros and creator x have a bearing at the top of the z rod. It is pretty easy to remove, easiest way is to remove the back, that gives you full access to the 4 bolts that hold the z stepper in the bottom. Remove these and the platform and z screw will drop out of the top support. Then you can dig the bearing out with a small screwdriver. Bolt things back up and put the back on and should be good to go.

haha, ya, it is easier to get to the bolts with the back off. That wobble is very common if the z rod is fully captured. It also depends on how badly it is bent. If mine was bent that much I would try to replace it or have a new one sent if it is under warranty.

Your pic looks like it may have a problem with a loose X belt! (it should be quite snug- almost pluck it like a guitar string)
A Z axis wobble shouldn't affect a print like that, as the Z axis is on two (quite firm) linear bearings/shafts
My FFCx never had a bearing at the top of the Z rod, just a plastic mount - with lots of clearance.
It did tend to wobble, dropped the Z stepper & machined a nylon bushing for the top..probably not necessary, but did it anyway..never affected anything.
