Printer slams into Y axis

What are you using to orient the model and create gcode?  If the start code is right, then maybe the model has been positioned somewhere off the bed.

Can you post the beginning of the gcode?

I had similar issues in the beginning.  Took me a while to figure out that the Slic3r and Repetier settings were the problem.
On my system, at least, the initial issue was that the dump area was specified as something like (150, 0, 0) which sent the head to the front right side corner where it would crash.  Being new, I had no idea that was the problem so I began using the manual controls to attempt a determination for the size of my printable area (left to right and front to back).  I turned off the dump area, but it still tried to go there.  Anyway, I ended up changing the size of my area in both applications to 150 x 140 to ensure I would not collide with the end of the printer in the Y direction.

I am sure I could go larger, now that I know about this.  However, since this is your first attempt at using it, you might look at the sizes and adjust them.  I found out the hard way that you need to go through a setup procedure to make sure the applications and printer are going to work together well (part of that is Ian's suggestion of the start and end gcodes).

This might not be your problem, but I thought I would mention it just in case. 

EDIT: After posting I saw that your gcode seems to be referencing larger dimensions than what is possible on the Solidoodle 2.
Looks like your settings are configured for 200x200x200.  I just tested and I am only comfortable with 150 x 149 x 150 on the Solidoodle 2.  Using 150 x 150 x 150 causes x,0,z to crash into the idler at the front of the machine (thats any X and any Z location).

On a side note, it seems like we should have a sticky on the forum to Ian's blog for setting things up and some other useful pages:
Something like "New Users Start Here" and then links to pages like this:

Anyway, I did a lot of reading before I got things working in a way that I felt was satisfactory and repeatable.  Others might benefit from having quick access to that as well. Besides, Ian and Lawsy and others have so much information already posted out there... it's a shame that it takes a web search and desperation to find it.
