Print Bed Loose?
Can anyone verify if their print bed is loose? If I place my hand in the middle of the heatbed, I can move the bed forward/backwards and left/right.
This seems odd to me, as my MK3S+ and MK4s do not do this. I am getting the same layer shifting and lots of VFAs. I have checked gantry, and done several calibration tests with the same results.

That is not right, mine is solid, rocks the entire printer. Start checking all the screws and attachment points.

Under my heat bed there are 3 white threaded standoffs, kind of in a triangle, 2 in the front one in the back. They move when the bed moves. Do yours have fasteners in them?

I assembled my C1 in october, and recently I noticed a printed part with horizontal holes... strange....
Checking all the bed assembly, I discovered the front left bed screw assembly was litteraly floating, leaving the bed only on 2 screws.
I did follow the assembly advice not too tighten screw there, but I was probably too respectful of the mechanics.
Now, as a regular monthly maintenance check (once every 50 prints) I check all the screws from the bed to XYCore assembly, making sure one day my Nextruder won't fall on the bed while printing 🙂

It may be a good idea to use light, hand-removable threadlock ("blue Loctite") on the metal-to-metal screws. It's not official recommendation, for whatever reasons (think possibility of royal screw-ups if it gets into bearings, over-achievers twisting heads off stainless screws...) but with vibrations and thermal cycling possibly quite obvious.

The Core One L has a completely different heat bed assembly. I have found no instructions or schematics on the assembly. Prusa has provided none either. They also claim the loose bed has no issues on the print quality.
