added parts to the CNC Torch Table assembly STP file. Still struggling with FreeCAD, but recent versions of freecad are getting much closer to production class. In my estimation, FreeCAD is currently the most suitable CAD software for Open Source Ecology development, in light of is open source code, and functionality. I am also impressed by openSCAD and SolveSpace, however they seem more useful for small 3D printable objects. Sketchup seems best for architecture.

As for the Torch Table, I will be devoting 100% of my "ample spare time" to it's development. I realize I may have been part of the bottleneck, by not yet finishing the promised exploded assembly drawings. However, I am also trying to comb through all of the documentation on the torch table (reptab) that OSE has accumulated over the years.

To me the Torch Table development/"design" can be broken down into 4 parts: 1) physical structure (frame, gear rails, gantry), 2) Electronics (arduino, stepper motors), 3) Software (arduino programming, STP file creation, Gcode creation), 4) clear and concise documentation that will encourage replication.

It is my understanding that the .step file format is the most compatible 3D cad format. It is based on ISO (International Standards Organization). when saving a 3d assembly as a step file, dimensions are preserved, and parts are segregated. The main problem with step files, (which is possible to overcome) is that if you design a cylinder by drawing a 2d circle and extruding it (push/pull), you can later adjust the diameter of the circle, which the cylinder diameter is linked to. In a step file, the 2d circle is lost, and it may be impossible to adjust the cylinder diameter.

The software I am currently experimenting with is as follows:

  • freecad
  • sketchup
  • solidworks
  • hypermesh
  • salome
  • openSCAD
  • catia

  • Started to draft a new version of the wiki's frontpage: Proposed Main Page
  • Starting FEM analysis on the CEB Press Press Foot. Investigating "tamper design" alternative.

Arrived at Factor e Farm today. Got some food and supplies from Dungy's and Dollar General. Purchased 2 boxes of probiotic formula for the HabLab septic tank. Added a full box to the tank. System should get a half box every month. Created a public expense list, with public commenting enabled, here.
