I have had a few of them running 24/7 since I released the files.
If have needed to add some tape recently behind the extruder mount to tighten it up, and on one of them I put a drop of glue on a rod that kept wanting to slide out (instead of replacing the bearing that must be dragging, I’m kinda lazy). Other than that I’m still pretty happy. Hope it works the same for you.
Thanks for the compliments.
