We purchased our S5 in July and have been using the same firmware version since then. (I think it was 5.2.11) Was pretty stable; only issues we experienced were when CPE or PC parts would sometimes detach from the buildplate and cause the Z axis to jam, then freefall and the printer would continue to print until it would complete the program. We had a few major material buildups; one time the bottom fan door axis broke right off but that is another story. Anyways, I noticed last week that there was a new update available - 5.2.24 so I went ahead and installed it. The printer acted a bit different (can't totally skip cooldown anymore!) but I didn't think much of it until I printed something overnight which also managed to detach and jam the head, almost breaking it for a second time. (Usually I check the progress but this time the camera wasn't working; neither through Cura or in the browser. If I see something odd I can pause or abort remotely). So then I checked for updates again and saw another one - 5.2.27, I installed it but the camera feed is still dropping out after a few hours of printing. The only way to fix this is to restart the machine, which means I can't really trust the printer on long, unattended prints. I would appreciate either a firmware upgrade which fixes these issues or help to downgrade to the last known stable release - preferably before the skip cooldown option was removed and where the camera feed was also still functional. We were planning on buying another S5 here at work but with my recent issues it is on hold. This is an expensive machine and it has to be more stable and dependable and less self-destructive.
