MK4s upgrade - noise on Y axis
Hello everyone,
I have an MK4 which I've just upgraded to an MK4S.
In this video: https://www.youtube.com/shorts/0UqvXs30o9Q you can hear that when the printbed moves to the limit of the y axis (as the bed moves fully back) there is a vibration/noise coming from the printer. It only happens at the extreme when the printer is printing on the lower edge of the print sheet. I've not had this problem before the mk4s upgrade. Actually I don't really print anything on that area so it's not really a problem now, I just noticed it when doing a first layer test (printing one layer on the full bed).
Does anyone maybe know what it can be from? When I upgraded to mk4s I of course needed to re-tune my belt tensions on the x and y axis (of course on the Y axis because I changed to the upgraded y axis parts) ; the x axis I guess had become loose over time.
Thank you very much
