Topic: Swapping Hot Ends on a Duo

Anyone have experience with replacing the Hot Ends on a Duo? My goals are:

- Be able to run just about any filament, including ABS, PLA, CopperFill, WoodFill, NinjaFlex, Conductive ABS, Carbon Fiber Filament and Magnetic Iron PLA
- Retain existing controller board and as much original hardware as possible
- Modify existing Repetier Formware as little as possible

The research I've done leads to believe:
- This can be accomplished
- requires a direct drive setup (as opposed to Bowden)
- may require sacrificing max print speeds
- may require sacrificing vertical print space
- will cost @ $250 + prints

I'm wondering if folks have suggestions on which hot ends might be a good fit (without devolving into religious wars) and if my assumptions above are wrong. Additional questions:
- can Davinci hotend carriage mods for single-extruders be realistically repurposed for dual-extruder models?
- are there existing dual-extruder hot ends (e.g.: Chimera) that can be used with the Duo, and if so what firmware mods would they require?
- is it realistic to modify only a single hot end or are the mods significant enough that I might as well do both hotends?

Thanks in advance

Re: Swapping Hot Ends on a Duo

It's up to you, most got with the E3D V6. It has a proven track record. Then there is PICO which is new but seems promising and is about half the size of the E3D which might be better for dual setups. The PICO will set you back 100 bucks each though. While the E3D is only about 75 bucks each.

Does the PICO do direct drive or Bowden only?

They sell both versions. Or you can buy the direct version and then the bowden kit.
