Finally got my extruder, and it didn’t fit a J-Head hot-end, although a 16mm spade bit made sure it did. The thin glass I was using on the bed also broke and the Kapton tape teared on the first go. Not a great start but it is all functioning, it just needs tweaking.
For the record, my replacement Solidoodle 2 parts still haven’t arrived, so if I can find a 200mmx200mm piece of glass or thick aluminum before it does, it’s fair to say their customer service needs adjustment..? Comments?
