We have had our Ultimaker 3 for several years and have followed the maintenance guide as best as possible (lubricating rods and lead screw, checking belt tension, etc). For the last several months, the printer has become quite noisy and it seems to be a mechanical noise, rather than the stepper or electronic drive noise. It's hard to figure out if we have missed a lubrication point or something similar? Hoping that someone with more experience can listen/watch the attached zipped video and perhaps notice something familiar as far as the sound and share how we might address?
Thank you so much.
