PID autotune

So I think I did something wrong…

After installing a new main board, I noticed my temps were fluxuating a little (not much, but as steady as they were), so I ran the PID autotune function (M303), and now, my temps are fluxuating even more!

See BOTTOM image:

Any thoughts? I ran the autotune twice to try and fix it, but same end result.

Got it to here. Am I asking too much for a smoother line?


Basically run a PID autotune and save to ROM with an M500 when done.
