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

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
