Hallo
Ich habe ein RADDS 1.5, 24V, und eine 40W 24V Heizpatrone.
Wenn ich versuche PID Autotune zu machen, dann wird das Hotend leider nicht heisser wie 140 Grad, obwohl die Zieltemperatur 230 Grad sind.
M303 E-0 S230 C8
Jemand vielleicht eine Idee woran das liegt?
Das RADDS zeigt keine Unterbrechung der Heizleistung an.
Ich habe im EEPROM diese Werte eingestellt:
#define EXT0_HEAT_MANAGER 1
/** Wait x seconds, after reaching target temperature. Only used for M109. Overridden if EEPROM activated. */
#define EXT0_WATCHPERIOD 1
/** \brief The maximum value, I-gain can contribute to the output.
A good value is slightly higher then the output needed for your temperature.
Values for starts:
130 => PLA for temperatures from 170-180 deg C
180 => ABS for temperatures around 240 deg C
The precise values may differ for different nozzle/resistor combination.
Overridden if EEPROM activated.
*/
#define EXT0_PID_INTEGRAL_DRIVE_MAX 205
/** \brief lower value for integral part
The I state should converge to the exact heater output needed for the target temperature.
To prevent a long deviation from the target zone, this value limits the lower value.
A good start is 30 lower then the optimal value. You need to leave room for cooling.
Overridden if EEPROM activated.
*/
#define EXT0_PID_INTEGRAL_DRIVE_MIN 60
/** P-gain. Overridden if EEPROM activated. */
#define EXT0_PID_PGAIN_OR_DEAD_TIME 24
/** I-gain. Overridden if EEPROM activated.
*/
#define EXT0_PID_I 0.88
/** Dgain. Overridden if EEPROM activated.*/
#define EXT0_PID_D 80
// maximum time the heater is can be switched on. Max = 255. Overridden if EEPROM activated.
#define EXT0_PID_MAX 255
Viele Grüße
