Description
After dealing with inconsistencies and backlash with the belt drive design, we decided to give the lead screw a try. We started with the Y-axis for the trial, and moved onto this X-axis upgrade.
##Y-axis lead screw upgrade is available here
##New! v2.0 X-axis lead screw upgrade!
Source files now available in Thing Files.
Notes:
All parts printed in ABS.
x-end right side.STL has in-file supports for the Z-stop. (There is an alternative file available with no z-stop.)
Top-Z-mounts and Bowden mount available for download in both 2 and 3-hole; uses standard Prusa frame hole dimensions. Mounts with the 625 bearing slots are available for threaded Z-rods that are approximately 300mm or greater in length.
X-carriage designed with a slightly larger 8mm smooth rod spacing (to accommodate the lead screw follower).
CREDIT: x-endstop holder.STL derived from ePoxi's Mechanical Y-EndStop holder for Prusa i3 (scad) here. Fantastic end stop to use. We recommend ePoxi's files for both X and Y axis end stops.

Test print is the Deprime test object found here on thingiverse
Running Repetier Host V1.0.6 and Slic3r V1.1.7
Natural ABS
.15mm first layer .2mm for the rest
30% first layer speed
45mm/sec perimeters, 70% outer perimeters
60mm/sec infill, 40mm/sec top layer infill
80mm/sec travel
25% honeycomb infill (just to show rapid changes in direction)
Higher print speeds are possible but, so far, this seems to be the best balance for quality.
