Hello,

here is my version of marlin 2.0 w
for A10 with dual extruder and single nozzle.
I made the choice to use #singlenozzle and not #MIXING_EXTRUDER
It's more easy to use with any slicer.

If you want to adapt for A20M you must change bed size and steps for extruders

look good.

Hello,

here is the purge bucket i use. With a purge bucket you don't need cleaning tower/ Filament change
https://www.thingiverse.com/thing:3623043

and the gcode i use in prusaSlicer.
In prusaSclicer you can't put personal Gcode in Extruder settings.
Then you must put "extruders settings" in "filaments settings".



start gcode "printer settings"

M117 Enable auto leveling;
M420 S1 ; if #define RESTORE_LEVELING_AFTER_G28 enabled in firmware whereas remove command and put G29 after G28
;----------------------------------------
M117 full heating...
M104 S[first_layer_temperature] ; set final hotend temp and continue
G28 ; go to HOME
G1 X0 Z1 F300
G1 X0 Z0 F300 ; stop leaking hotend
M109 S[first_layer_temperature] ; final hotend temp and wait for it
M190 S[first_layer_bed_temperature] ; and wait for it
M140 S[bed_temperature] ; did not wait full first layer to fully warming bed

if you have bltouch and don't use #define RESTORE_LEVELING_AFTER_G28 in fimware, you must do a G29 after G28 start printer gcode

Hello,

could you explain what i didn't understand ?
Thanks

Hello,

I appreciate learning things (yes, yes really).
You say intersting things.
But why in a so rough way ?

Thanks
