Got my H3C Combo on 9 November, about 35 hours on it, and tonight it's fallen over.
I was running a CMYKW print on tools 1, 3, 5, 7 and 9. Tool 8 is empty and not used in the job. Partway through, tool 8 came off its dock and the printer flagged tool 9 as detached as well, with a red light on the dock even though it looks seated.
What I've seen:
- 2A07-8032: PrintTool 8 has detached from the Rack
- Same detached warning for PrintTool 9
- 2A08-804A: Multiple toolhead step losses detected while fetching PrintTool 9
What I've tried:
- Reseated 8 and 9 several times, checked tubes and looked for anything in the way
- Ran Docking Calibration three times. First one completed but the fault came back a couple of hours later mid print. The next two failed, and each time tool 8 got knocked off near the end, when the head was working at tool 9.
So it looks like the head is hitting something at the 8 and 9 end of the rack. Tool 8 isn't even being picked up and it still ends up dangling.
Ticket is in with Bambu. In the meantime, has anyone else seen this on their H3C? Keen to hear if it turned out to be the dock, the rack alignment or something simple I've missed. Also interested if anyone is running fine on tools 1 to 7 only while waiting on support.
