hey there,

can someone tell me the variable for the gcode to set the firstlayer nozzle and bed temperature?

i only found the variable for the "normal" print temps, but not for the firstlayer.

    But there is a setting for the first layer temp in Cura.

    If i set this

     

    M140 S{material_bed_temperature} T0 ; Heat buildplateM134 T0 ; Stabilize bed temperatureM104 S{material_print_temperature} T0 ; Heat right extruderM133 T0 ; Stabilize right extruder temperature

     

    the printer is heating to print temp and not the set first layer temp.

    You'll see cura use 2 g-codes.

    The fist time temperature is set (is first layer temp)  M109 is used, which means execution of the rest of the code will wait until the set temperature is reached.

    Further on in the g-code the temperature is set using M104, meaning the temperature is adjusted to this set temp but execution of the rest of the code will not wait till this temp us reached.

    So if you set first layer temp to 205, and print temp to 200, you'll first find a M109 S205 and further on a M104 S200.

    No, i cant use the auto generated temps of Cura, because it breaks my print start.

    So is have to use the variables in my start gcode. But the variable {material_print_temperatue} set's the print temp and not the first layer print temp.

    i need something like {first_layer_print_temp} or so.

      • 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
