The X ends now have much stronger bar clamps and the nut traps are moved to the top for less lead screw wobble. X motor bracket now has two screws in the front of the motor and one at the back allowing it to be much smaller. The Z couplings now use neoprene tubing instead of PVC and close completely. The tube end caps are now nut traps to allow the tube to just have a single hole. The rear fixing blocks now have the central screw going the other way so have onyl two nut traps. The extruder springs now have washers to increase the default tension. The spool holder now has the washers on the outside of the spool. The carriage fan bracket has been strengthened. The fan duct now has a hole to cool the top of the hot end. Small printed parts now aggregated onto one build plate. Hole in the Wade's big gear increased slightly. The heat shield is now 5 layers of cardboard instead of foil and an air gap. Bom generation and exploded view mode can now be enabled on the command line. The assembly diagrams for the manual are now built from the command line. Some mods for the Huxley version but still broken. Fixed the long ATX bracket holes ending coincident with the face. Can now have non square print beds. Cap screws now shown silver instead of black as now all BZP. Now shows the motor wire position. % operator no longer used for transparency as OpenScad behaviour has changed. Now includes the Skeinforge and Pronteface configurations on the SD card of priovided in the kit.
Limitations
-----------
Currently only supports mendel and sturdy machine variants, the huxley version needs more work.
Use
---
Add the directory of the OpenScad executable to your search path. For Windows OpenSCAD-2012.02 or later is required. For Linux it will need to be openscad-2011.12 or later.
To get PDF versions of the sheet drawings add InkScape to your search path.
To make all the files for a machine run
make_machine.py machine_name
To make just the bom, sheets or stls run bom.py, sheets.py or stls.py machine_name.
machine_name can be mendel or sturdy. To make your own variant copy scad\conf\mendel_config.scad or scad\conf\sturdy_config.scad to yourname_config.scad. Then run make_machine yourname.
To view the model of the whole machine, open scad\main.scad. It will take several minutes to render (about about 8 minutes on my computer) but after that you can pan and zoom it at reasonable speed and changes takes less time to render. (Note: main.scad will only render correctly if conf\machine.scad exists, which is created by the make_machine.py script.)
To view a sub-assembly, open the individual scad files. Set the exploded flag in config.scad to make exploded views.
To get blender renders of all the parts put blender in your search path and run render.py machine_name.
