Update: If you are looking for replacement glass.. I found it on the cheap! Check out the details and instructions here https://makersteve.com/2018/08/06/finding-cheap-replacement-glass-for-he3d-k280-or-any-large-delta/
.. is a capable printer but you’d better be ready to put in some work. It will take a day or two to put it together, and a week to make it print. 4 months later, I have not successfully got the Dual Extruder to print.
Instructions are a little light and you may want some spare parts.
Difficulty: High / 15+ hours (to several months) to complete
This printer is BIG… 280x280x600MM, BIG.
A friend and I each purchased one of these at the same time. We both opted for the Dual Extruder and 3D Scanner package. Came to $544.00 during Cyber Monday-ish time.
My power supply failed and HE3D shipped me a new one.
My friends glass was broken, they told him to buy some new glass. We just used a 12 x 12 inch mirror tile temporarily. I did find replacement 300mm x 3mm glass on Ebay
I would not be telling the truth if I said assembly was easy, however, it was also pretty fun.
Where do I start… This was a pain to assemble. Because of the unclear instructions I found myself taking the same sections apart and reassembling because I didn’t do it right. After about 15 hours, I was read to attempt to print.
Then I found my Repetier firmware would not support the Dual Extruder. HE3D’s support is good, not great, but good, and Pinkney provided the firmware required. I used Repetier-host initially, it is still the best way to adjust the firmware EEPROM settings but I print with Cura.
Pros: BIG print space, cost, DUAL Extruders! Runs on Octoprint just fine after insulating the underside of the bed.
Cons: thin cables break, no fan mount solution for the upgraded fans on the Dual Extruder, so I designed a mount based on the HE3D Mods provided by prahjister, and few printable mods. Did I mention I haven’t cracked the code on making the dual extruders work? Also, prints come out about 98% of the actual size. My Creality CR-10 prints to the expected size every time. Again, the wires are thin, I broke the thermister wire but was able to solder it back together and cover with heat shrink.
My Dual Extruder Fan mount in action. I was printing the Little Red Box and they came out great.
YUGE! The HE3D K280 dwarfs my Creality CR-10. I had to install the wall fan and control unit because my taste buds were off and I was developing a cough with 3 x 3D printers running. The Wall fan was also a requirement because of some Alt-coin mining; more on that later.
I will add some detail on leveling and the Dual Extruder and 3D scanner in action soon.
I really like mine, but I am always up for a challenge.
