I also printed this cube http://www.thingiverse.com/thing:271736 And it printed PERFECTLY but everything else prints with shifting layers I don't understand why...

Have you tried printing that yet? It can be more helpful in seeing what is going on.

Before i print the calibration steps i was actually in the process of printing this gear and it so far seems to be very helpful. It showed that both the x and y axis was off. Still dont know why the cubes printed fine but printing this gear helped show which direction it was off and by how much without using much filament. Im now printing the calibration steps given from Raykholo to see if this prints well **fingers crossed**

I'm pretty sure that my pots are way more jacked up than they need to be and I'm not experiencing this issue. I would opine that you not worry about turning the pots too much up. I don't think your results will be much worse. You can always back then down later.

Do the cube, let's see what happens. I would also recommend trying the t-nut on the download page. http://www.gmaxprinter.com/?page_id=146 Do it, increase by the specified turning increment, try again, you get the drift. I've seen other people succeed at calibration that way, with the t-nut that is.

Printed the cubes and a Squirtle model with success my attempt to print the gmax wire clips failed miserably layers shifting once again. Im printing the Gmax T Nut now...lets see how it goes.

With the cube that looks more like a poor cooling issue to me... I had results similar to but worse than that when I first assembled and ran the unit without any fan installed. Is your fan on?

Is the squirtle supposed to look that way?

I'd jack up the pots a bit to get that test out of the way. If squirtle were facing forward or backward while printing, increase your Y pot.
If facing sideways, increase X pot.

Test the adjustments with the t-nut.

I agree with Ray that my pots are probably turned up higher than they need to be as well. The only pot I turned down since I have been running the printer was the extruder stepper pot. (and I had turned it up first) The X,Y and Z pots all seem to work fine being turned up. I started with the small steps, but then just went for 90 degrees or more to get past the shifting problem.
