whenever I try to heat the heated bed to a target temperature, I get that error 10 degrees before reaching the target. I also noticed that the value of the constant PID_FUNCTIONAL_RANGE in my configuration is 10 by default, and that is the same value as the gap between the actual temperature and the target temperature when I get the error.
I would upload my config but I’m a new user so it doesn’t let me upload it. If you want to know a certain part of my config just let me know and I’ll copy paste it.
I am using 2.0 nightly build on a ramps and arduino mega 2560.
