We just got the next batch of Creality Dual Extruder boards in. They have been added to the site. You can get one here: Creality Dual Extruder Upgrade Board = CR-10/CR-10S/CR-20/Ender 3 – Includes Motor + Cable
The new bundles allow you to add extruders at a discounted price as well (Tough Extruders and the Aluminum ones).
We are running low on the 2 into 1 adapters and the dual hotends but they are on order and we should have more of them next week. Both of those bundles with the 2 into 1 adapters and the dual hotends can be backordered so please note if yours is in backordered status.
Dual Hotend Bundle: https://www.th3dstudio.com/product/cr-10s-dual-extruder-bundle-dual-hotend/
Also after testing the CR-20 is also supported by the dual extruder board and it is already setup in our Unified Firmare to support it!
Thank you everyone! Have a great weekend!
