Overall, been about as good as can be hoped for. This guy is at just over 7k hours, and the only thing I’ve really had an issue with was force sensors on the bed got replaced at about 5000 hours.
Anyway, what I’m getting here is I came back to a failed print where the cover had been knocked off the head. Cleared it out, tried to print again, and failed the Z-axis part of homing.
Then I noticed that the right side of the bed was about half an inch lower than the rest. So, I followed the procedure to fix it, and then I home, and I get this (watch the right side- action is at about 21 seconds): https://photos.app.goo.gl/GquKYkb5UsxCcyAVA
For those who don’t want to watch the video, what we get is that during the homing the bed goes all the way to the top during the process, we hear a ‘clunk’ and the right side instantly slips down…I don’t know, call it half an inch.
I can’t even really think of HOW something can slip down a threaded rod like that, much less what my cause could be here. Or why it only happens at the top.
Can anyone offer any suggestions as to what I should be doing to fix this? Yes, I’ve put in a case, but we know how long the turnaround time can be, and we’re probably not fixing it in the first round trip.
