Drawing parts (1 / many)

Pending the arrival of the last parts, I decided to start designing some modifications I plan to incorporate in my printer.

First things first though. So activities of yesterday's and today's evenings were:

  • Install OpenSCAD 3D modeling software which seems to be the favorite amongst the freeware loving builders/makers community.
  • Learn the OpenSCAD scripting/programming language. Luckily it comes with the decent manual and there are quite some interesting lessons on Youtube.
  • Design a first thing to get a feel of OpenSCAD. I chose to design a 'parameterized' new version of a pulley for a string driven Rostock (preset for M3 nuts and bolts). Came out quite well,... I hope (can't print it yet, so I hope to get some feedback from my readers or from people downloading it from Thingiverse.
  • Post the pulley on Thingiverse for everybody to use www.thingiverse.com/thing:36951

Build Status Update (part 8/many) - Platform moves!

Just a quick update. After finishing the assembly of the frame and the linear motion, I could finally install and test the platform. Turns out the steppers missed some steps every now and then, but the platform moved. Goal for the day achieved. Next step is taking care of the 'misstepping steppers'.

Below a short video (if there's no pic, it didn't happen).
