Extruder 2 start heating when it starts to print

Hi


Have adual extruder. When start Printing heatbed and extruder 1 is heating op but not extruder 2. When heatbed and extruder 1 is up to temp, it starts the print and the heating of extruder 2, it is the support som it does not get heated Before is starts to print. How to solve this?

I solve it but start it manually.

  • Make sure the start gcode contains something like

    M109 T1 S200

    to heat up and wait for target temperature. Mest is to add first
    M104 T1 S200
    before all M190/M109 commands so all heat in parallel before waiting. I guess your start gcode just has wrong initialization here.

    Thank you

    I have this code:

    ; Default start code
    G28 ; Home extruder
    G1 Z15 F800
    M107 ; Turn off fan
    G90 ; Absolute positioning
    M82 ; Extruder in absolute mode
    {IF_BED}M190 S{BED}
    ; Activate all used extruder
    {IF_EXT0}M104 T0 S{TEMP0}
    G92 E0 ; Reset extruder position
    ; Wait for all used extruders to reach temperature
    {IF_EXT0}M109 T0 S{TEMP0}

    {IF_EXT1}M109 T0 S{TEMP1} Can I do like this?

  • Yes but do not forget
    {IF_EXT1}M104 T1 S{TEMP1}

    as well for faster heating.
  • Thank you for your help=)
