Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, ...)
I have a CR-10 and octopi has worked fine in the past but for some reason lately the temp. has been all over but its slowly getting better .

That's a problem with your printer, not OctoPrint. You might want to do some PID tuning.

3

thank you I did some research after your comment and fixed it now I know what PID is and How to tune it

4

umm, my temp is soo crazy it cant be tuned it's "too hot" what should I do?Recv: PID Autotune failed! Temperature too high

You might want to jump on the support forum for your printer. They may know what types of things you'd need to do to make sure that your thermistor's value is correct in your firmware, for example.
