After a while the original Techzone Huxley X carriage with a single bronze bushing started to get sticky, despite of any oil I fed it. It created some massive backlash on the X axis, so I designed this :
Used to replace the original single bronze bushing X axis carriage with 3 LM6UU linear bearings.
Includes holes for mounting a better attached hotend (with a peek block retaining the nozzle).
Parts needed :
- 1 printed X carriage (this file).
- 3 x LM6UU
- 2 x 6mm smooth rods, length 300mm (to replace non-metric original techzone X rods).
Based on PRUSA Mendel X-carriage by Josef PrÅ¯Å¡a
The Openscad file, along with any dependencies needed, is in the zip archive.
Added ziptie holes to secure the linear bearings.
2) Fit the 2 belt attaching M3 bolts that goes under the LM6UU (might need to use the soldering iron to push those in).
3) Snap LM6UUs in - you might want to secure them using zip-ties so they don't move - I had to open holes with my dremel for that. Feel free to add holes to the design :)
4) Dismantle your X axis
5) Remount your X axis, replacing the 6.56mm non metric rods with 6mm ones and the old X carriage with this new one.
