When does this ever happen?
What? A free upgrade? When does that ever happen? This is completely against my experience with other 3D printer manufacturers. I'm lucky if they answer my emails, let alone do it within a couple of hours with a free upgrade. Flashforge came out with a new hotend for the AD5X 2nd run machines. I have one of the original release machines. My hotend had a tendency to clog, but this new hotend is supposed to help with those issues.
