prime stampe con problema su asse x [Risolto]

buongiorno a tutti
Sto facendo le prime stampe con una prusa i3 ma come si vede dalle foto ho un problema sull'asse x che non riesco a risolvere.ho provato la V sui driver e risulatano tutti 0,4V e ho provato a scambiare driver e motore ma niente il problema rimane.ho ricontrollato la parte meccanica e sembra tutto apposto.Sto usando sprinter su arduino mega 2560 e repetier host come programma.vi posto le impostazioni dei movimenti su sprinter:


// This determines the communication speed of the printer
#define BAUDRATE 115200
//#define BAUDRATE 250000

//// MOVEMENT SETTINGS
//-----------------------------------------------------------------------
const int NUM_AXIS = 4; // The axis order in all axis related arrays is X, Y, Z, E
#define _MAX_FEEDRATE {250, 250, 2, 45} // (mm/sec)
#define _HOMING_FEEDRATE {1500,1500,120} // (mm/min) !!
#define _AXIS_RELATIVE_MODES {false, false, false, false}

#define MAX_STEP_FREQUENCY 30000 // Max step frequency

//For the retract (negative Extruder) move this maxiumum Limit of Feedrate is used
//The next positive Extruder move use also this Limit,
//then for the next (second after retract) move the original Maximum (_MAX_FEEDRATE) Limit is used
#define MAX_RETRACT_FEEDRATE 20 //mm/sec

//-----------------------------------------------------------------------

// Min step delay in microseconds. If you are experiencing missing steps, try to raise the delay microseconds, but be aware this
// If you enable this, make sure STEP_DELAY_RATIO is disabled.
//#define STEP_DELAY_MICROS 1

// Step delay over interval ratio. If you are still experiencing missing steps, try to uncomment the following line, but be aware this
// If you enable this, make sure STEP_DELAY_MICROS is disabled. (except for Gen6: both need to be enabled.)
//#define STEP_DELAY_RATIO 0.25

///Oscillation reduction. Forces x,y,or z axis to be stationary for ## ms before allowing axis to switch direcitons. Alternative method to prevent skipping steps. Uncomment the line below to activate.
// At this Version with Planner this Function ist not used
//#define RAPID_OSCILLATION_REDUCTION

#ifdef RAPID_OSCILLATION_REDUCTION
const long min_time_before_dir_change = 30; //milliseconds
#endif

//-----------------------------------------------------------------------
//// Acceleration settings
//-----------------------------------------------------------------------
// X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
#define _ACCELERATION 1000 // Axis Normal acceleration mm/s^2
#define _RETRACT_ACCELERATION 2000 // Extruder Normal acceleration mm/s^2
#define _MAX_XY_JERK 5.0

#define _MAX_ACCELERATION_UNITS_PER_SQ_SECOND {1500,1500,100,2000} // X, Y, Z and E max acceleration in mm/s^2 for printing moves or retracts


// Minimum planner junction speed. Sets the default minimum speed the planner plans for at the end
// of the buffer and all stops. This should not be much greater than zero and should only be changed
// if unwanted behavior is observed on a user's machine when running at very slow speeds.
#define MINIMUM_PLANNER_SPEED 0.05 // (mm/sec)

#define DEFAULT_MINIMUMFEEDRATE 0.0 // minimum feedrate
#define DEFAULT_MINTRAVELFEEDRATE 0.0

#define _MIN_SEG_TIME 20000

// If defined the movements slow down when the look ahead buffer is only half full
#define SLOWDOWN


const int dropsegments=5; //everything with less than this number of steps will be ignored as move and joined with the next movement

quando devi inserire del codice, usa la funzione code, in modo che sia tutto più chiaro. Non conosco bene sprinter, ma non credo sai un problema di firmware, piuttosto una perdita di passi.

guarda qui:

sotto skipping steps

Ciao,
La letteratura definisce codesto fenomeno effettivamente perdita di passi.
Buon uso del tasto cerca ;-)

grazie per il link!!provo a ridurre di nuovo le accelerazioni....vediamo!

ok ho cambiato firmware!sono passato da sprinter a marlin e......non ci sono piu i problemi sull'asse x!!!!!!sicuramente ho sbagliato qualcosa sulla configurazione di sprinter perche mi ritrovavo con valori anomali su step per unit.comunque adesso stampa bene e devo solo rivedere la configurazione per l'home sull'asse z.
