Teaching Tech | Conditional PID tuning for maximum hot end stability - Is it worth it? @TeachingTech | Uploaded 5 months ago | Updated 2 days ago
Check out my 2nd channel, TT Racing: youtube.com/@TTRacingYT
I personally only tune my hot end PID for a single temperature wit the part cooling fan at 100%. But perhaps a lot more accuracy and stability can be found with conditional PID tuning. In this video, I take you through what PID is, how to tune it, and how to tube it for various scenarios and apply the, in the slicer. In theory this is superior, but in practise the effort may not be worth the meagre returns. What do you think?
Thanks to Bob Sissan for the request.
