Stall Detection at de begining of a print



  • Hi,

    Now everything work perfectely on my printer except the begining of a print.

    When my print starts, it assume that the bed is allready probed and only do a homing with G28.
    But after the probing, the head goes to 0;0 and pose the print due to a stall detection.

    In the past I allready experienced this error but I'am unable to fin the thread where you give me the solution.

    Here are my gcodes :

    HomeAll.g:
    M98 P"homex.g"
    M98 P"homey.g"
    M98 P"homez.g"

    HomeX.g:
    M913 X50 ; reduce motor current to 50% to prevent belts slipping
    G91 ; use relative positioning
    G1 Z5 F6000 S2 ; lift Z relative to current position
    G1 S1 X-700 F4000 ; move all carriages up 700mm, stopping at the endstops
    G1 Z-5 F6000 S2 ; lift Z relative to current position
    G1 X10 F6000 S1
    G92 X0
    G90 ; back to absolute positioning
    M913 X100 ; motor currents back to normal

    HomeY.g:
    G91
