Printer hangs after hotend and bed reach temperature

I humbly suggest looking here:

Discussion/Proposal: small heater control improvements

This is just a proposal. Problem: PID can oscillate too much for some users. While printing because of large hot end flow changes or powerful fan, hotend can temporarily lose temperature. There are several attempts to change something in PID or propose different solutions to that problem (MPC, velocity PID, other calibration methods). I personally think there is a minority of users with such problems, and I feel like my solution is mostly “duct tape”. There are 3 patches: Allow configure…

Maybe instant PWM or more frequent query of heater + shorter smooth time will improve things.
