Topic: Swapping Da Vinci 1.0 Board with Pi?

I have a Da Vinci 1.0 running Repetier, otherwise more or less factory standard issue.
.
I think I blew the on-board fuse that powers the extruder head plug.  In fact, if my multimeter is to be believed, this is exactly what I did.  Tried today to fix this issue with a jumper, but Parkinson's had other ideas.  Now I have 1) a printer that doesn't heat at the extruder but is otherwise fine and 2) a giant mess (ok, a really small, annoying mess).
.
So, I was looking into replacement boards because I figured the cost would be lower than my frustration is worth to try to make this board work.  Looks like factory board is $150, but RAMPS is like $40....
.
I already have a Raspberry Pi running with this machine.
.
How much effort would be required to make that Pi B+ power the printer directly?  I see a bunch that run RAMPS through an Arduino (yeah yeah, it's in the name...) but I don't see anything similar for Pi. 
.
I will be the first to admit I'm no expert here, I just want to get my printer back up and going, I can handle a little coding and lots of hardware that doesn't involve sloshy things like soldier or glue.  Ha ha (Parkinson's joke ... ba dum bum).
.
The other thought I had was that maybe there's somewhere on that board i can pull enough juice to split off a lead to run to the extruder plug directly.  Obvs. it would need a fuse of some sort so I didn't burn the neighborhood down, but I can't find a circuit diagram to tell me where to go grab that from. 
.
Any ideas?  This horrible thought would basically be a splice off of the power supply or from a point on the board where the power has already been stepped down to the right level.

Raspberry pi are not a control board. If you cant afford an oem board put a ramps on it

You can do a ramps conversion then use a pi for wifi remote control like you are doing now.
the ramps conversion is not for the faint of heart you will likely need to splice a couple of wires replace end stops and a couple of other components. there are a couple of write ups on this forum of how to do the conversion.
