Pid Tune 50W

[diettelo]

I cant get Pid Tune my Nozzle
Got 50W but i goes over the 15 degree
Autotune failed.
Can you increase the amount?
Happens even on low temp
Also on v17 or v19 from your Firmware

Suggested PID values for 50W heater on UM2:
P,I,D
5, 1.2, 50 -- basically the 25W values from UM cut in half
5.6, 0.35, 23 (neotko recommendations for 35W then multiplied by 35/50)

Either of the above values should work quite well. You can be off by quite a bit from ideal and still get great results from PID controller.

To keep autotune from failing you could tune with fan on 100% and nozzle close to the glass bed. Or you could tell autotune to tune on a higher temp like say 260C but this second option is a worse idea and not as realistic to normal printing conditions.

How can i go close to the bed? With menu only or do i need a computer?
Do you have M codes for me?
