I just performed my first 3 month maintenance on my H2C. While cleaning and lubing the induction hot end rack I inadvertently knocked one of the hot ends off the rack and didn’t notice it. Then when trying to move the bed up and down the loose hot end got stuck between the bed and the hot end rack and this bent one of the hot end rack rails that hold the hot ends. There is only a few millimeters of clearance between these rails as they move up and down past each other and with the bent rail they wouldn’t clear each other so I kept getting errors when trying to move the bed up or down. Fortunately once I noticed the problem I was able to remove the loose hot end put it back on the rack and manually bend the bent rail back so there was sufficient clearance. This was entirely my fault due to my stupid clumsiness and not paying attention. So I’m making the post to caution others that when doing maintenance or mucking around inside the H2C make sure all the inductive hot ends are all correctly in place on the rack before moving the bed up or down. If you get an error when trying to move the bed up or down do not proceed until you have found the problem and made sure all of the inductive hot ends are in the correct positions.
