Topic: Help with custom installation of an extruder (Modding a DaVinci Jr 1.0

My current 3d printer is an old DaVinvi jr. 1.0, and so far it has irrevocably clogged two extruders. Rather than continue paying $100 apiece for replacements, I have decided to modify the extruder to use an E3D v6 by replacing all the electronic bits with a RAMPS and an Arduino. This hopefully lets me use the existing frame and motors and stuff.
          My plan is to cut down the main plastic frame of a dead extruder to a flattish plate that still mounts to the current carriage. The problem is, I don't know the melting point of the original extruder plate, so what I'd like to do is have some kind of spacer that I can use to mount the extruder. The plan is to use some car repair adhesive to stick the spacer to the fan box of the E3D and mount that to the old plate, thereby not having the extruder in direct contact with the little piece of plastic.
         But, as a relative noob in the world of homemade printers, I have not had much luck finding a suitable spacer for the job. I'd also like to hear any thoughts on my overall plan before I burn down the house and fill the build plate with pile upon pile of plastic spaghetti.... So... Help me please....

        Also, does anybody know if the stepper motor controllers in the DaVinci are built into the main board, or are they somewhere between that and the motors?

The stepper drivers are hard soldered to the main board.

You don't have to do RAMPS conversion to use E3D clones, you will just need to print a E3D mount and wire the heating element and themistor to the small board. You can find multiple different design of E3D mount for Jr. in thingiverse. Replace the E3D themistor with stock themistor in case the themistor come with your E3D clone is incompatible.

If you don't currently have working 3D printer to print the E3D mount, try replace the PTFE tube in stock hotend throat, that is where stock Da Vinci Jr. hotend usually jams, you will need to pre-heat the hotend to 180C before you can dissamble the hotend so be careful don't get yourself burned.
