these seem to work well for me, your mileage may vary 
snug up the belts, then loosen the set screws on the rear pulleys - work the carriages back and forth until everything moves smoothly and is properly aligned, then tighten the set screws.
with the carriages all the way back you should just be able to pinch the 2 sides of the belt together midway between carriage and idler pulley - there should be just a little resistance - and both sides need to be the same tension.
]]>I still have grinding and vibration, but randomly. If I reset Y belts and pulleys I can get a few prints out fine then sound comes back. If I do Y pulleys again I can get rid of sound for a few prints. I have my Y belts very loose.
I would recommend to anyone to use a Direct Drive Y setup and get rid of that small belt that bends your Y axis shaft.
]]>I am still working on my calibration cubes and have change my extruder ratio based on instructions given. now right after I get done with the brim passes and starts on the skirt I get a big glob in the corner of the print and ever pass that corner just gets messier, any idea why?
Also, I am getting a vibration noise when it runs in the Y axis. The cube comes out perfect for x and y dimensions and I let it build up a good amount of layers and there is no skipping occur. Any idea regarding this vibration and noise?
Post a picture.
As for vibrations, does it vibrate on the y when it's not printing?

Sorry for stating so poorly, I am already printing cubes, just tweaking after printing each cube

On my SD4 with the stock hotend, I run the following:
PLA - usually between 165 & 170C
ABS - typically 200 - 205C
Different brands may vary a little more from those, and each machine is a little different - kind of need to run a temp calibration print (search thingiverse) to figure out what is going to work best for you/the material you are using, but the above temps should get you in the ballpark.
if the layers are easy to split apart, increase temps in small increments (2-3 degrees) until they are adhering well without being sloppy.
]]>So none of you think it is a temperature related issue?
I was just about to post something like this. So I do
Do what heartless said above!

Set the extrusion multiplier to 1 and print a single wall calibration box (20mm x 20mm x min of 10mm high - height doesn't matter too much as you will be stopping it before it prints fully anyway) with these settings;
perimeters - 1
top layers - 0
bottom layers - 2
infill - 0
on the print settings tab, under advanced - your default extrusion width should be set to 0.48 for the stock SD hotend (0.4 nozzle)
1st layer = 100% (or more, I use 100% and it works fine)
leave everything else at zeros for the default width
start the print, let it get 5-10mms high and kill the print.
remove the box and measure wall thickness on each wall (try to only get one or 2 layers for your measurement) with your calipers making a note of what the measurements are.
add them up and average. you are shooting for a wall thickness of 0.48mm - chances are the walls will be thicker than that for the first print in this calibration.
use the measured average to calculate what your extrusion multiplier should be set to
example:
measured wall = 0.52 averaged
formula: 0.48 (desired size)/0.52 (measured size)=0.923....
0.923 is what you enter into the extrusion multiplier box - save the profile, re-slice your box and print again - measure and average and make adjustments as needed to the extrusion multiplier to obtain a wall thickness of 0.48
additionally - every roll of filament will be different - this calibration should be done for each new roll you run.
You can save a new profile for each roll if you change colors frequently like i do (I have roughly 30 rolls, all different colors/materials) just be sure to name it appropriately so you know what profile goes with what roll.
Check your Retraction Length and Speed settings under Slic3r Configuration (Printer Settings Tab - Extruder 1).
Try increasing the speed and length a bit and see how that works.
