    If I leave in (#define CUSTOM_EVENTS) the host repeater is giving this error (communication timeout - reset send buffer block repeater host)

  • RAyWBRAyWB

    that is a sign that the Hardware is not running correct !!!

    so check what i wrote in last two answers

  • LeandroBLeandroB
    Okay, I'll go look
  • LeandroBLeandroB
    I tested the communication between i2c and PCA9685, and all the outputs are working well, I tested with leds and multimeter
  • LeandroBLeandroB
    I'm doing something wrong when putting folders in Repetier-Firmware
  • LeandroBLeandroB
    the error (communication timeout - reset send buffer block repeater host) only appears when I put the (#define CUSTOM_EVENTS) Configuration.h, when I do not put the repeat host works

    so please generate github account and upload your complete Firmware so i´ll take a look a it

    alternatively just post your configuration.h and i´ll try to Setup a package this weekend and post it on my github


    btw, what´s the result of i2c scanner?

    This was the result of the i2c scanner
  • LeandroBLeandroB
    I deleted pwmtest, and PCA9685 worked fine

    thats the problem....
    Adress is set to 0x41 in CustomEventsImpl  line 30

    change to 0x40

    the hint with i2c scanner is also written in line 33/34
  • LeandroBLeandroB
    Hi RAWWB, now the repeater host is running smoothly, thanks for the help, now I just can not connect the laser, would you know what it could be?
  • RAyWBRAyWB
    edited June 2018
    what do you mean with cannot connect the laser?
  • LeandroBLeandroB
    The PCA9685 board is not sending PWM signal at output 15, to control the laser, output 0 is all the time with 5v
  • LeandroBLeandroB
    I changed from output 0 to 15 on line 35 of CustomEvents.h, output 15 is set to 5v (#define EXT_LASER_PIN 0 // PIN Number from PCA9685) (#define EXT_LASER_PIN 15 // PIN Number from PCA9685)
  • RAyWBRAyWB
    and what command do you send with repetier host?
  • LeandroBLeandroB
    I used the M03 M05, G1 G0, M452 C1 M452 C0
  • LeandroBLeandroB
    This is the Firmware I'm using (https://github.com/nobolx/Repetier/tree/master)
  • LeandroBLeandroB
    I used the M106 e M107 
  • LeandroBLeandroB
    My X-axis 14,000, Y 19,000, Z 540.00, I 6.050

    X min
    ENDSTOP_PULLUP_X_MIN (Switch on GND, normally closed)

    Y min
    ENDSTOP_PULLUP_Y_MIN (Switch on GND, normally open)

    Z min
    ENDSTOP_PULLUP_Y_MIN (Switch on GND, normally open)

    X max
    ENDSTOP_PULLUP_X_Max (Switch on GND, normally closed)

    Y max
    ENDSTOP_PULLUP_Y_Max (Switch on GND, normally open)

    Z max
    ENDSTOP_PULLUP_Y_Max (Switch on GND, normally open)

    Homing order
    HOMING_ORDER Y, X then Z

    1 . Change configuration.h

    delete the entry in line 22

    #define LASER_PWM_MAX 4095

    (you have to set it in Line 217)

    Change

    #define LASER_PWM_MAX 255  to

    #define LASER_PWM_MAX 4095


    2. Gcode

    M03 Switches laser on , m05 off

    to set PWM value You have to use the M03 followed by S value  (value from 0 to 4095)

    so code can be:

    M452

    M3 S410  // set Pwm about 10%

    G1 X50 Y50 F400

    G0 x0 y0  // Laser off during  G0 move

    M3 S820  // set PWM about 20%

    G1 X0 Y100 F400

    M5  //Laser off

    G1 x0 y0 //(g1 move with laser off)

    BTW : Laser Settings in configuration .h (beginning at Line 213 in your configuration.h)

    #define SUPPORT_LASER 1
    #define LASER_PIN -1  <------   Keep , as pin is set in custom events
    #define LASER_ON_HIGH 1 <----  change to 0 if laser is on with M5
    #define LASER_WARMUP_TIME 0
    #define LASER_PWM_MAX 255 <---- set to 4095
    #define LASER_WATT 2 <---- Change to value of your Laser



    and tip for future :

    READ COMMENTS in  files..... all your Problems with laser were well commented  ;-)



  • LeandroBLeandroB
    Hi RAWWB, I want to thank you, for having patience to help me, now it works right \ o / kkkkkk, I'm sorry to bother you so much, thank you.
