I have recently been getting a Hotend holder homing blocked (0300-8024 215506) error with my H2C, but there is nothing blocking it. Once I hit resume, it does the homing angain and starts printing.
I turned the printer off and moved it to see if there is any resistance and it feels fine.
I think it started happening after the last firmware update.
Is anyone having a similar issue?
Check that one of the hotends is not disengaged and lying somewhere in the rack.
I checked inside my printer and bumped the N°6 hotend with my arm in the process. I had not noticed it until I found it stuck on the rack against the window. In my case it did not block the rack so I could still print without it but it could as well blocked the rack and I would have gotten this error.

Thank you. Mine had fallen off and gotten wedged in the chain!
I bump #6 with the build plate a lot, even got wedged in the rack and had to get rough with it once. One area I think could stand some creative engeneering.
