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.

HiThank youI 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?BR

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

as well for faster heating.
