Geeetech G2s Upgrades

****Superceeded by v2 at http://www.thingiverse.com/thing:2157448****

This is a series of upgrades for the Geeetech G2s printer. The stock unit has a number of design issues that I wanted to address to get better prints.

The upgrades are printable parts, to be used with some sourced components.

I've included the master assembly as both STEP and native Fusion360.
Before printing, consider calibrating/compensating for material shrinkage. I've made a utility at http://www.thingiverse.com/thing:1982686 to assist in this - but use whatever method works for you.


1. New Carriages.
The stock carriages use 2 cheaper bearings. The short contact length and slop results in a significant amount of play when the effector changes direction, putting torque on the carriage. In my case, I found this to be up to .300mm as measured by a good quality dial indicator when near to the towers. These new carriages show under .02mm deviation.
These new carriages use 2 additional linear bearings.
