M104/109 Heats both extruder


Recommended Posts

Posted · M104/109 Heats both extruder

Hi there 
I recently installed a inductive probe to my printer which has dual extruder (Not sharing nozzles) 
Here is the starting of the issue I want to use G29 before every print I did this by adding G29 to start g-code but the problem is nozzle heating before calibration and oozing too much when print starts it leaves the oozed plastic in the prints first layer which can cause problems (also some prints of mine needs glass like first layer and ooze is problem for this)
So to resolve this issue I did edit start G-code like this


M140 S{material_bed_temperature}

G28 ; home

M190 S{material_bed_temperature}


G29 ; auto bed leveling

M109 T0 S{material_print_temperature}

M109 T1 S{material_print_temperature}

G1 Z0

G1 Z15.0 F6000 ;Move the platform down 15mm

;Prime the extruder

G92 E0

G1 F200 E3

G92 E0


After calibrating completes it heats both of the extruder even if I chose T1 to print with it still also heats the T0 which is a bigger problem for ooze
Also what I noticed is {material_print_temperature} set extruder to 210 but my extruder temp is set to 190 on cura I don't know why this problems hapening also I don't know how to solve these 

few notes to consider
G28 not set Z to 0 so nozzle is not touching to build plate this is why I have G1 Z0 it is to prime the extruder
Also while calibrating nozzle is not touching to build plate so heating it makes no sense
