asse z

salve a tutti,

ho alcuni problemi col firmware.. uso repetier, però non riesce a far funzionare i motori dell'asse z e non sente i finecorsa.. ho provato con sprinter e i motori dell'asse z funzionano... qualcuno sa dirmi dove potrebbe essere il problema nel firmware?

Da inesperto potrei dirti che magari non è un problema di firmware...dato che che un programma funziona e con l'altro no! I motori proprio non si muovono? Perdono passi? Lascio comunque la parola a chi se ne intende più di me!

Gli endstop sono ottici o meccanici, in repetier devi settare falso se usi gli ottici qui,

// ## Endstop configuration ##
// ##########################################################################################

/* By default all endstops are pulled up to high. You need a pullup if you
use a mechanical endstop connected with gnd. Set value to false for no pullup
on this endstop.
*/
#define ENDSTOP_PULLUP_X_MIN false
#define ENDSTOP_PULLUP_Y_MIN false
#define ENDSTOP_PULLUP_Z_MIN false
#define ENDSTOP_PULLUP_X_MAX false
#define ENDSTOP_PULLUP_Y_MAX false
#define ENDSTOP_PULLUP_Z_MAX false

forse l'asse zeta va troppo piano, se i motori sono collegati alle barre filettate in ZAXIS_STEPS_PER_MM dovresti avere un valore alto,

// *******************************************************
// *** These parameter are for all othe rprinter types ***
// *******************************************************

/** Drive settings for printers with cartesian drive systems */
/** \brief Number of steps for a 1mm move in x direction.
For xy gantry use 2*belt moved!
Overridden if EEPROM activated. */
#define XAXIS_STEPS_PER_MM 71
/** \brief Number of steps for a 1mm move in y direction.
For xy gantry use 2*belt moved!
Overridden if EEPROM activated.*/
#define YAXIS_STEPS_PER_MM 71
/** \brief Number of steps for a 1mm move in z direction Overridden if EEPROM activated.*/
#define ZAXIS_STEPS_PER_MM 2560
#endif

come è settato Z_MAX_LENGTH, forse sei già a fine corsa, per le prove io l'ho settato a 300

/ maximum positions in mm - only fixed numbers!
// For delta robot Z_MAX_LENGTH is maximum travel of the towers and should be set to the distance between the hotend
// and the platform when the printer is at its home position.
// If EEPROM is enabled these values will be overidden with the values in the EEPROM
#define X_MAX_LENGTH 250
#define Y_MAX_LENGTH 250
#define Z_MAX_LENGTH 300

ciao...
grazie, si era un problema con gli endstop... c'era un true dove doveva esserci un false

Thank you Carlob,

I had had problem same, now i solved it.
Thank you very much.
But i have problems not solved in Repetier firmware.
I use Lambo board and Honeywell thermistor.
When i connect my printer, temperature start from 56 degree C and the heater do not work.
How can i solve these problems?
Help me.

hi aikol, dont know lambo board, but for honeiwell thermistor ther is a post on reprap forum repetier,

repetier forum

i hope that will help

Thank you carlob,

I uploaded my printer as you teached me,but the temperature is same and heater do not work.
When i use Marlin firmware, herter do work except thermistor.
Can you help me to solve this problems?

Best regards,
aikol

If your card is a rambo, on the wiki page of your card there is that this might be useful :
----------------------------------------------------------------------------------------------------------------------------------------------
Firmware

Support for RAMBo is in several firmwares.

For Marlin you will at least need to set the following variables in configuration.h:

#define MOTHERBOARD 301

The TEMP_SENSOR needs to be set to match your configuration. For a Epcos 100K thermsitor on Extruder0 and HeatedBed:

#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1

You will likely need to tune the PID and DEFAULT_ settings to mach your hardware.

For some computers you may also need to set #define BAUDRATE 115200 to get communications.

You can adjust the motor driver settings in Configuration_adv.h: #define MICROSTEP_MODES and #define DIGIPOT_MOTOR_CURRENT
-------------------------------------------------------------------------------------------------------------------------------------------------------

do a search from the RepRap general forum for your card.
