Data
- SSR - 5 hz max reliable switching frequency. [1]. 0.5 hz recommended for heating.
- Overshoot is 10-30C on the bed. D3D_v20.04.27_Data_Collection#Hysteresis_of_Bed
Code
M303 S50 E-1 C5 - 5 passes, set for 50C, -1 for bed
Procedure
PID Autotune - [2]
Results
Extruder
Using Lulzbot Cura, M303 with no parameters heats the extruder to about 150:
And produces optimal values of P, I, D
M503 displays current values:
< M503
...
< echo:PID settings:
< echo: M301 P22.20 I1.08 D114.00
You can save the values from PID Autotune by going into configuration.h
Bed
- PID autotune would have to be enabled for the bed in configuration.h.
- If one is using an SSR, can this be used with default switching frequency of Marlin? Let's look inside Marlin - Configuration.h
