Printrbot + Upgrades [X-bridge, Extruder Mount, Y-Clips...]
by PolakiumEngineering, published
These files include all of the parts I designed for improving my printrbot.
For a complete description of my modifications read here: http://polakiumengineering.org/?p=1905
The final revision is now uploaded, all of the tolerances should be perfect for properly configured printrbots.
9/24/12 - X-stop is fixed in place, non-adjustable
10/04/12 - Motor mount now compatible with 28mm 36 Tooth GT2 Pulley
10/09/12 - Added LME12UU compatible parts. (See notes)
03/01/13 - Replaced by V2.0
For more pictures and complete build instructions go here:
If the alignment of the Z-stop is off, heat the arm of the motor mount with a torch/lighter/heat gun, then bend and hold the arm to its proper alignment until cooled.
- Tolerances for the length of the LME12UU bearings are very close. Fitting the bearings may require additional finishing. One way of setting the bearings is to soften the plastic with a torch/lighter/heat gun before pressing the bearings into place.
