Hexagon Hoopla - Hot End fell out


I am supporting a Taz 5 with a Hexagon extruder for a Co-working space.

Purchased a new hexagon extruder to replace one that got jammed with PLA. However as I was printing with it, the entire heater block came off like so:

Is there any hope for repairing it? We have another new one on order, but would like to repair this one as a backup.

That appears to possibly be a knockoff hexagon (or possibly one of the 1.75mm ones?. The real ones that I have seen don’t have an insert tube like that. You can just buy a new barrel from Itworks3d.com but they appear to be out of stock at the moment https://itworks3d.com/product-category/parts/3d_printer_hotends/

your other option is to glue the tube back in place using a thermal transfer epoxy. Artic silver makes a good one that should work if you aren’t printing nylon with it.

Hmm… the packaging looks legit. :slight_smile:

I’ll try the silver epoxy though.

Huh, yeah that looks like legitimate packaging. Maybe they changed the design since the last one I bought.

Sorry to hear about this issue with the hotend! It looks like a set screw may have been missed on this hotend that keeps this tube in place. If you can contact us at support@lulzbot.com or fill out our support form here: https://www.lulzbot.com/support we can see about getting a replacement.

Nope, that is “How It’s Made”! :laughing:

The inner tube is pressed fitted into a threaded outer sleeve, and it looks like this one failed. Or at least a number of them I have seen were.
