Re: Temperature drop from 208 to 195

I have been trying autotune PID three more times:

P - 76.38
I - 3.50
D - 416.74

P - 55.12
I - 2.26
D - 335.92

P - 224.02
I - 29.47
D - 425.75

Very inconsistent values. Is this normal?

Set with: M303 S215

Last time printing, the hotend temp dropped from 210 to below 180.

Here is a picture of the hotend, I hope you can see this:

I have taken out the metal washer and put a piece of circular wood board to keep the heat from travelling up in a straight line.
