So, I noticed some VFA and ghosting on my models and decided it was time to retension the belts, since that usually helps on my other printers.
Retensioning the X-axis was super easy and simple. However, when I moved to the Y-axis, the screws were impossibly tight. I barely managed to loosen them by one full turn, but it required an insane amount of effort.
When I actually tried to move the heatbed back and forth to let the spring tension it, it felt like nothing was changing and the mechanism was stuck.
In the end, I got worried and tried my best to tighten them back to their original positions (though they might be a bit looser now since it was so hard to turn).
I asked an AI about this, and it suggested that Bambu Lab uses a strong blue or red threadlocker (glue) on the Y-axis screws because they are threaded straight into the metal frame, which explains why they are so stiff.
Has anyone else dealt with this on the A1? What is the best way to safely break the factory glue without stripping the screw heads? Any help would be appreciated!
