It would be nice if we could have Processes like in Simply3D where I could divide up a model between certain layers. To better change settings. I want to add extra cooling for my top layers but there is no really easy way to perform this task. Other than to just Ramp up the Fan speed. But I want to have the fan speed set to 10% and then for the top layers set the fan speed to something like 50%. But just for the top layers. Also it would be nice to do things like slow down the print speed at X layer height, etc. Maybe I can add a Marlin Gcode line to do this in the mean time. But not the best option.

    The Search and Replace post processor (Extensions / Post Processing / Modify Gcode then "Add a Script") has some good options that can help.  It accepts multi-line replacements so you can do something like this:

    Search = ;LAYER:200\n

    Replace = ;LAYER:200\nM106 S127\n

    Use regular expressions = Checked

    (The "backslash+n" is a newline character and they are required as shown.)

     

    You could lower the fan speed (if needed) by adding another Search and Replace.

    Search = ;LAYER:204\n

    Replace = ;LAYER:204\nM106 S26\n

    Use regular expressions = Checked

      • 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
