Sensor type for MicroMake?
February 25, 2016 08:57AM
Hi, my hotend won't go up to 200, only to 193 degree. I am wondering what is the correct sensor type? I am using 5:

100K thermistor, ATC semitec 104GT-2

My printer is Micromake, firmware is latest Marlin RC, I downloaded Micromake's old marlin firmware, it is also 5.

I just run PID tuning command: M303 E0 S200 C8

It reaches 195 then wouldn't go up anymore and consoles says timedout, pid tuning failed.

this is my current pid setting:


//===========================================================================
//============================= PID Settings ================================
//===========================================================================
// PID Tuning Guide here: [reprap.org]

// Comment the following line to disable PID and enable bang-bang.
#define PIDTEMP
#define BANG_MAX 255 // limits current to nozzle while in bang-bang mode; 255=full current
#define PID_MAX 175 // limits current to nozzle while PID is active (see PID_FUNCTIONAL_RANGE below); 255=full current
#if ENABLED(PIDTEMP)
//#define PID_DEBUG // Sends debug data to the serial port.
//#define PID_OPENLOOP 1 // Puts PID in open loop. M104/M140 sets the output power from 0 to PID_MAX
//#define SLOW_PWM_HEATERS // PWM with very low frequency (roughly 0.125Hz=8s) and minimum state time of approximately 1s useful for heaters driven by a relay
//#define PID_PARAMS_PER_EXTRUDER // Uses separate PID parameters for each extruder (useful for mismatched extruders)
// Set/get with gcode: M301 E[extruder number, 0-2]
#define PID_FUNCTIONAL_RANGE 10 // If the temperature difference between the target temperature and the actual temperature
// is more then PID_FUNCTIONAL_RANGE then the PID will be shut off and the heater will be set to min/max.
#define PID_INTEGRAL_DRIVE_MAX PID_MAX //limit for the integral term
#define K1 0.95 //smoothing factor within the PID

// Ultimaker
// #error
#define DEFAULT_Kp 22.2
#define DEFAULT_Ki 1.08
#define DEFAULT_Kd 114

#endif // PIDTEMP
