Recently I have been trying out more complicated prints that require support material, high detail, and/or high amounts of precision and I would like a second extruder for support material and for quicker infill on precise prints that don't require complex supports. I currently have a prusa I3 pro B with a single extruder and I don't completely understand the process of upgrading and would like some help with the steps on how to do so. Thanks.

I'm also curious about trying out a more precise hot end with a .2 mm diameter, but I don't where I would buy something like that.

Hi，
You can update the latest firmware to achieve more functionality，and here is the download link：

AS for the hot end with a 0.2 mm diameter,you can consult our seller.

thanks for the reply, but I was wondering about what parts I would need to upgrade.

You don't have to upgrade any parts on the Pro B. You will need another hot end and extruder, the plate that came with my Pro B is the same as the Pro C.
You should be able to just add the new parts and flash the firmware and be on your way.

Sorry, I misunderstood your meaning yesterday, As Newopint95 says, you need to add new parts and flash the firmware, and here are some items can help you :
1. A 20A power supply:

Thanks for the help. I ended up getting side-tracked over the summer so I haven't gotten around to doing this until now.

Looking at both parts lists, the major expenses will be in both the control board (GT2560+5 A4988) and the dual extruder (MK8 dual extruder). What I currently have in place of those parts are an GT2560+4 A4988 board and a single MK8 extruder. So i'm wondering if its possible to:
1.Buy an additional MK8 extruder and fabricate a housing for both my old one and the new one giving me the same thing as the dual extruder
2.add an additional port to the control board.

1. You can do it by yourself.
2. The board has two extruder port. Just use it.
