Bed heating at the end of the start gcode

[StrDa121]

Hi, My start gcode is executed before the bed heats up to the target temperature. The nozzle is heated first and then the bed. The same start gcode don't cause problems in prusaslicer.

can you please upload your slicer project files and a sliced .gcode file thank you.

Somewhere in the start G-Code you should find:

"M140 S[first_layer_bed_temperature] ; set final bed temp"

In my configuration it is placed after homing

Maybe you did not mark the "Bed" when you made the new configuration for the printer

with your current configuration the slicers "start g-code" does not contain any commands to heat the bed the only place it gets inserted is on line 889(after your 'start g-code') and 1543(other layers target) you need to add M190 S[first_layer_bed_temperature] in the relevant location in the "start-gcode" i would also recommend ticking this box, after you have fixed the slicers "start g-code" so it will use the klipper macros.

just an FYI, you shouldn't have these sections filled in how they are. for klipper you should be using the macros, your slicers "start g-code" box should contain something like below and your klipper macros should be configured to accept the slicers parameters

print_start HOTEND={first_layer_temperature[initial_extruder] + extruder_temperature_offset[initial_extruder]} BED=[first_layer_bed_temperature] CHAMBER=[chamber_temperature] MATERIAL=[filament_type]

Thanks. I added M190 S[first_layer_bed_temperature] to my code and it works.
