I am starting my conversion of my Mark One. I already have a Mark Two so I don't need the fiber capability in the One. I am replacing the brain and extruder/hotend. I am going to make it into a high temp printer hopefully. I want to print PEI, PEKK, ans possibly Peek.
Brains: Duet 3 mini 5+
Extruder: Bond tech BMG X2
Hot end: Slice Engineering Mosquito Magnum X 2
We will see if I can make it work.
