I noticed my made a loud whiny noise while calibrating. I cleaned it since I had done some mess draftboard engraving.
I had noticed when I took the lens out of the head it was not pushed all the way in. I chalked it up to me moving it about or perhaps the bed got bumped by someone not wanting to tell me.
Either way, after cleaning the whiny noise (not like the normal im moving noise) was gone.
It’s been maybe 4 hours of use and the whiny noise is back again. So once again, I thought I guess ill clean it again.
When I went to pull the lens out to wipe it down, I noticed once again it was not nestled all the way in. So I pushed it back in with the tool. It has not fixed the additional whiny noise I am hearing.
It has been much colder in our place, I am unsure if that is a factor into the different sounds I am hearing. But I’d much love to have someone tell me this is normal operation and not to worry.
