We’ve been busy working on updating our firmware again to support the CR-10S Dual Extruder Board we sell to be supported in the Ender 3 printers.

We have released 2 updates to make this happen along with a bugfix for Anet boards and adding in a setting to change your hotend X distance when using dual hotends like our Tough Dual Hotend, E3D Chimera, or Dual Independent hotends.

Marlin is used on over 90% of printers worldwide.
