2017-04-17's week

Continue task of previous week to create video of y axis assembly based on script part 1

Tasks:

• recreate video as Marcin suggests [1]
• pay attention to details of video editing guidelines [2]

Deliveries in a zip

Notes:

• FreeCAD Python basics
  • Change camera view with python console [3]:
    • get current position: Gui.activeDocument().activeView().getCamera()
    • set a position: Gui.activeDocument().activeView().setCamera('long text returned by previous get command')
  • separate multiple commands in one line with ;
    • example: make carriage transparent: FreeCADGui.getDocument("D3D_Mini_Sub_Assembly_Axis_Y").getObject("Universal_axis_carriage_side_01").Transparency = 80;FreeCADGui.getDocument("D3D_Mini_Sub_Assembly_Axis_Y").getObject("Universal_axis_carriage_side_02").Transparency = 80
  • Create a Macro script to change view during the playback then associate a hotkey with it associate an icon with a macro
• Timing of FreeCAD's Exploded Assembly : I used only "Animation steps" parameter to adjust playback time. The duration of playback became longer when vokoscreen added some cpu load.

Time log : (I will sum up at end of week) 17 Apr: 1.5 h meeting
18 Apr: 1 hour reading (wiki contents), 2.5 hours struggling with the assembly video.
20 Apr: 2h20mins wiki readings + getting basics of freecad macro to set camera viewpoints and doing freecad exploded part animations with the freecad mini y axis created by Emmanouil.
21 Apr: 5:30 continue exploding in freecad + learn basic of video editing of kde + put together the assembly video + upload files

Task description:	Create assembly animation of Y Axis of D3D_Printer (script part 1)
Completion percentage:	69
Link to results:	in progress Assembly script's part 1 voice [7] FreeCAD file [8] video only[9] kdenlive project file [10] final video [11]

Hints

• Install exploded parts module of FreeCAD and start exploring the exploded parts animations. If it freezes then install latest version of FreeCAD and the module itself.
• The instructional videos of FreeCAD_101 are the good examples how it should look like: no major pauses, continuous voice
• 30 sec video should show 15 minutes of assembly which can be created in 1 hour. On the workshop each module will be built at the same time if someone completes his/her own then helps others. The instructional video will be played in a loop.
• The bolts in the axis should all be M6x18, not M6x25
• Link to meeting minutes within D3D_Log[12]
• Jose has a 12" printer Jose_Log, CAD file can be downloaded from there. 10 April 2017 18.page suggests extruder realignment
• If a part does not appear in part library Part_Library or in Emmanouil_Log then send e-mail to Marcin. To make things simpler the total amount of parts should not increase.
• Exploded part helps with assembly [13] but the one on the link was not complete : missing some of the magnets. One carriage has 6 magnets : one on each corners and one on middle of long edges. Picture does not show everything but the description text of assembly details that. Magnets can be assembled with superglue and pushing for 15 minutes until glue hardens.
• The modules ( Axis Motor Side - Chas, Carriage Side - Jean Baptiste, Idler Side - Roberto) can be used in the Y Axis video.
• Every FreeCAD file should remain modifiable.
• Signup to network.opensourceecology.org's 3dprinter developer group and ask questions there [14]
• Join OSE workshop Facebook group
