PID Autotune values rising?

[truenorthtrader]

Hey folks.

I'm a bit concerned when I do PID tuning it's rising almost every time just a bit, is this an indication of a problem?

My recent PID Autotune results averaged

#define DEFAULT_Kp 100.63
#define DEFAULT_Ki 6.53
#define DEFAULT_Kd 389.76

Do I have to do this every time after I try and calibrate the X,Y,Z, motor's?
thanks!

No once should be fine, you'll get different results every time you run it, it's an iterative process, it's dependent on things like ambient temperature and it only does 3 iterations and the initial values matter.
As long as your hotend it getting to temperature and holding it within a reasonable bound say +/-1 degree forget about it.

Thank you again fine sir!!
