I have been “secretly” learning from CN for a whole and really appreciate the great advice/suggestions offered here. This is my first post and please forgive me if I fail to follow the posting rules.
I just received my new CEM40 mount and noticed some strange noise while tracking and slewing. I have emailed iOptron (and my dealer), but would really love to hear your opinions! Here are detailed description and two short videos I recorded —
Upon testing the CEM40 mount I noticed some strange noise. While tracking at sidereal speed it makes a rhythmic sound, and while slewing at various speeds it makes large sanding/vacuuming sound multiple times in the middle (mainly from RA motor). This occurs with or without OTA.
I have uploaded two short videos on YouTube recording the sounds. Please find the link below —

Any comments/suggestions would be greatly appreciated!
Thank you all and clear skies!
