Mini v1 making some strange new noises

Hi
I’m about 10 prints in using my lulzbot mini
And its started making some strange loud shuttering noises so I powered down and restarted print all seems fine now but just making sure that I dont need to check or adjust any settings as I’ve heard the noise several times now ?

I Have a video of the printer producing the sound but not sure if I can post a video here or not.
Thank you for any info.
