Flow thermostat - a Cura plugin

Several years ago I built and experimented exensively with an Ulitmaker 1 which is a filament deposit 3D-printer. I then focused on high speed printing and investigated what limits how fast you could go. Here are my raw datasheets from that time.

I used the data that I gathered to write a crude "Flow thermostat" Cura plugin which aims to connect temperature control to the individual layer cooling time. Then the printer will use high temperatures for high flow and low temperatures when printing slowly (for example pointy details). When set up correctly, the printer would always use the maximum flowrate possible and adjust feed and temperature down when it would have otherwise caused overheating. Since I didn't maintain the pluging it stopped working when Cura was developed further. However I see that someone has built on my code since then, I found this repo now and hope to revitalice the plugin one day.

Recovered data

Raw data used in plugin design

I was able to print very large very fast with consitent quality using the plugin when it was tuned for a specific roll of plastic. If I remember correctly the narrow 200 mm high drop printed hollow in 1 h with 3 walls 0.2 mm layers and 0.4 mm nozzle diameter.
