Show HN: Prosur: Logs all 3D printer activity in a DB, view it all in a browser (github.com)

After much frustration in trying to reliably log data from my custom 3D printer with a heated chamber, I wrote this tool. I eventually decided to go all-in and make something very robust, and expand the scope to collect not just chamber temperatures, but images, print jobs, slicer settings, motor positions, etc. as well. The tool displays all data in a single plot, which scrolls all the way back to 1970 and allows zooming out. The left sidebar shows print jobs, while the right sidebar shows slicer settings for the currently-viewed job and allows downloading the original print file. The graph will auto-update every second. The bottom bar shows a timeline of images, matching the x-axis of the plot above.

After so much tinkering with my 3D printer I have developed a mindset where I want to base any descision I make on data. At this point I'm able to print reliably with my FDM printer. The key parts are the Z-probe (BLTouch), rigid bed, heated chamber, bed temperature (110 deg C), glass surface with ABS slurry. This setup is reliable for me and has no deformation of the parts. Prosur is still needed as I always find myself tweaking slicer settings for each print. Also when switching filaments, tuning is needed. Having data (collected by prosur) to back up your tuning descisions makes the whole process feel more systematic.
