Lately my BambuLab A1 Mini has been making a squeaking noise only during the first 2–3 layers of a print. After that the noise stops. It sounds like it’s coming from the Z-axis lead screw, but I’m not sure why it only happens at the start.
I’ve cleaned visible dust and checked for loose screws, and I dug into greases — I’m stuck between buying Camp Grease NLGI-2 or Camp Grease PTFE. Everywhere people recommend Super Lube, but it’s very expensive here.
any tips on diagnosing the noise?
the printer seems to work perfectly fine, without any issues regarding print quality.
