Progress on assembly and animating first step. Learning more Freecad details as I go. I've animated a rod rotating into the carriage. The rest of part one should be easy now. I am curious how the belt animation will go.

Today on the D3D Part Library page I see there is some question of stable parts and/or versioning differences. This was effectively what I was trying to ask for clarification on at the end of the meeting Monday. I rewatched some of it after it was posted on YT because it is often hard to hear others because of audio quality. I am assuming we are doing the assembly documentation because the printer design is mostly finished and those parts are just being pulled out of the full assembly or other files, especially since the Universal CNC axis was effectively finished in 2016. But, I see the File:D3D CAD Assembly.fcstd doesn't have all the small parts fully assembled in it like the bearings and the plastic clam shell halves aren't ready to break down as needed for animation yet in that file anyway.
Earlier, I was wondering if I could quickly use an existing file with x-axis delete the other parts and start animating, but looking at the full assembly file and the instructions being otherwise I decided I'd be better off just following the steps and importing parts as needed. This method might help with Freecad stability and speed too. I am not as far along as I hoped mostly due to being busy. I spent time skimming through some YT vids on animation, but I find just diving in and experimenting with the actual work to be faster more like hands-on learning. So far I think the actual explode and animate operations will go quickly once I have it re-assembled.
I recorded all my audio while it was late and quiet. I exported to ogg and then started editing some noises out in audacity. It is easy to edit, but timing and the natural speaking rate can get confused as well if too much of the pauses, breathing, and mouth noises are cut out. I recorded the whole thing in one file; Each step can be edited out into separate files easily. I am not sure if that is slower than recording each step and exporting to ogg files individually. Seems like the video will need to be longer than the audio or have pauses between steps for assemblers to finish their tasks.
I also understand my animation task better from looking over the other scripts more. Next, I'd like to animate the rods to rotate clearly into the carriage assembly. I think I can make that visible to the users if the appearance is right.

I examined the full D3D CAD Assembly and searched for some of the parts in the script and found photos and video so I understand the parts assembly better. I tried some explode functions again on the CAD file just to see how best to create move paths and FreeCAD closed suddenly, so as always saving often is a requirement. Now I'm working on importing parts and getting the positions & orientation correct.

Hint: Examine the D3D Overall assembly File:D3D CAD Assembly.fcstd and you can at least see how everything fits together - then the video script may make more sense if the overall assembly is good
Continued reviewing the D3D docs and video guidelines.
Experimented with parts explosion on the simple x axis example.
Read over the x-axis script.
I may need to understand machine function and assembly a little better to choreograph the parts animation, but the recording audio to each step should be easy during some quiet time; I think speaking at a moderate pace loud and clearly using my headset mic shall suffice and I have used audacity in the past so minor audio cleanup and timing/speed adjustment can be done in post. Ubuntu does not appear to have audio hardware/driver support for common sound hardware functions such as noise cancellation and beam forming, but they can be done in software on the CPU in real-time to improve mic input. Looks like a lot of potential redundancy in the axis assembly except maybe different bolt hole patterns I am not yet familiar with.
Downloaded Video Intro Template as .svg and test loaded into kdenlive to save project start.

Installed EPA work bench into FreeCAD and I am continuing to review info on Exploded_Part_Animations

I saw I missed the "to fit" function on the bolt in my cube so I looked for it in freecad; I ended up setting it to 27mmx240mm instead of 2.54mm, since that looked best. I see bolt thread ID/OD options and I see a multi hole align option for bolts in assembly2. I also need to understand the measure tools better.

Busy with WWOOFers on the farm, but I finally did finished editing my freecad test video and uploaded to YT. I had some clips and a pause in work and the end only showed the finished cube for a split second so I made edits to clean it up and get it exactly 30 secs. kdenlive seems to crash often when I right click clips in the media list, but avoiding that and saving changes often helps. Other than bugs it is easy to learn including the effects. I had recorded in 8fps x264/ogg and at first thought the framerate conversion would be an issue, but it did a great job.

Had some bugs working with Kdenlive, but managed to click everything just right finally so almost done editing; Overall it is fairly intuitive to use and the GUI is nice once you learn them.

Finally finished editing my sketch, but crashes in Freecad have left with me with several clips to edit together so I've been looking at kdenlive tutorials. Very nice NLE that looks fairly easy to use.

Having an issue with vokoscreen not saving the video file. I suspect the pause function being faulty, which I used before resuming and stopping when I was finished with freecad and wanted was thinking of taking a break before loading kdenlive. I got hung up on aspects of the sketch mainly positioning it, but I had given up on constraining it effectively when I shifted it around and surprisingly managed to properly constrain it. I need to go back over some functions related to mapping sketches to faces I thought I understood. Looks like I need to test vokoscreen a bit more see where the bugs are and then record again. I've been recording at a low frame rate since that seems sufficient. No point in recording at 30fps when it will be decimated to 30 secs anyway. I'm also using more open codec settings, which I assume work. I did see it save test clips before. I need to go through the kdenlive tutorials as well and I think I'll record my editing as well.
