Dual extruder printing with smoothieware

Posted (edited) · Dual extruder printing with smoothieware

Hi,

I am using Cura 3.0.3 and my board is using Smoothieware. I choose Marlin Gcode flavor. Cura sets extruder temperatures like this:

 

M104 S260  ; I believe this sets the first extruder's temperatureM104 T1 S260  ; and this should be second extruderM109 S260M109 T1 S260

 

It seems Cura assumes that M104 T1 S260 command will set the second extruder temperature without selecting it. However, my firmware is changing the tool wherever she sees Tn command. And, according to this post, this must be the standard behavior of a machine.

So, if someone is experiencing the same issue, or a developer could change the software accordingly, I will be grateful for any help.

    I have no idea about Smothieware, but i have to disagree this argument:

     

    However, my firmware is changing the tool wherever she sees Tn command. And, according to this post, this must be the standard behavior of a machine.

    In case of Marlin, that's simply wrong. A standard Marlin firmware will never do a toolchange for M104 or M109. The (optional) T-parameter is interpreted as the target extruder for the temperature argument and nothing else.

    If Smothieware behaves different, the "Marlin" Gcode-flavor is probably not the right choice.

      • 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
