THANK YOU!
Looked all over for this.
the "print_temperature_layer_0" part was missing on all the other sites.

Thank you !

Thank you!

Really appreciated... thank you. I've extended this slightly given I have the CL Touch bed leveller so after the G28 which resets bed levelling I run M501 to load the bed-levelling settings previously saved to EEPROM followed by M420 S1 Z10 V to enable bed levelling.

"M106 S0 ; Turn off cooling fan"
"M107 ; Turn off Fan"
Hmmm...
M106 S[0-255] sets the speed of fan, so sending "M106 S0" will turn of cooling fan.
M107 only turns of all of the fans, ofc if index was not given.
Sooo... I think one of these strings can be removed, or...?

CAN you be more specific ?

I think what he's doing is something like this in between G28 and M117:

M109 S{material_print_temperature_layer_0} ; Wait for Extruder temperature
G28 ; Home all axes
M501 ; Restore EEPROM settings
M420 S1 Z10 V ; set bed leveling state
M117 Purge extruder
G92 E0 ; Reset Extruder

I haven't tried running it yet but so you might have to test for yourself too.

Can anyone fix the code so it don´'t run 5 min bed leveling and instead just load what is saved in EEROM. I don't want to mes up something.
And can anyone pls optimize the code becaus it first preheat the bed then level then heat the nozel. Can't we heat the bed and nozzel at the same time. Isent it gona be bether if we moove the m190 and m109 to the end of the start gcode before the m117

i iknow, thats too old, but i put this code on prusa slicer for my ender 3 and the error screem show,

16128.gcode failed due to invalid custom G-code sections:
end_gcode
Parsing error at line 9: Not a variable name

i need a gcode when finish my print, before the heat low, i need to retrat the filament for i remove

I will see if I can send u the new g code I use it's pretty conviniant. I had table with auto bed leveling but now everything works ass it should. На вт, 21.11.2023 г., 22:27 ч. pseudobamboo ***@***.***> написа:
