UPDATE: I got it!! just had to type "pip install requests" in cmd prompts, and then the full string command worked!
quick rundown for anyone still struggling on windows:
-download python
-download ffmpeg
-download timelapse.py
-download ultimaker api (unsure if this is required, but just to be safe)
-move python exe, ffmpeg exe, and timelapse.py to the same folder.
(worked for me with just these files, I didn't have to move any extraneous folders or files)
-open command prompt from the start menu
-Navigate to the correct folder in command prompt by copying file path from the top bar in the file explorer, then type: cd <filepath> into CMD Prompt
-type pip install requests to make sure python is up to date and ready
Running the script post-install/setup:
-Open cmd prompt
-Navigate to folder by copying the file path and typing: cd <filepath>
-Type command as follows:
python timelapse.py HOST DELAY OUTFILE
Replace HOST text with IP address of printer.
Replace DELAY text with desired rate of capture, in seconds. 30 will take a photo every 30 seconds, etc.
Replace OUTFILE text with the desired resulting video file name. e.g. timelapse.mp4.
-It will wait for the printer to start, and tell you where it’s saving images to the local app folder. -It does take images while setting up print and heating up, and during any pauses in print.
-The computer must stay on and running during entire duration of print, cura does not have to be running at all.
-Once completed, the video will be saved in the same file location as the code.
-If it’s not opening in QuickTime, media player, or any other basic players, open in VLC or Premiere and save out again.
