Posted · strange no print zone at front and back

Hi there

I am having issue with strange no print zone on ender 3

I have a Mac M1, it did work for a while, even after moving to cura5.2 but not anymore and I was trying various printer then those zone appeared and can't get rid of them

I deleted Cura, deleted Cura folder in library ( Macintosh HD\Users\[user_name]\Library\Application Support\cura)

restarted from scratch with 5.2.1, just set basic ender 3 V2 did not touch any setting other then increase bed size to 300 x 300 to give a better visual on no print zones

zones are still there, the position of them does not change with bed size

If I load a custom printer set to 235 x 235 zones are not there

I am including a picture of issue and a 3mf file, hopefully someone can figure out the issue

It is an issue because it limit the print size front to back to barely 190 mm, I have printed gears up to 210 mm in diameter

thanks for Cura

    Hey @jacprint,

     

    Thanks for your report 👍

     

    I tried to reproduce your issue but I'm missing your specific configuration to print with. 
    Because on my side it looks as expected:

    Do you have a project file for us? It contains the printer and settings we need for troubleshooting. 
    To save a project file go to File -> Save project.

    CE3E3V2_gear60Cyclo.3mfHere you go

    Also added a square shape 190 x 190 mm , there is free usable space on the sides

    but not front and back, I have printed on the same machine with Cura 4.6 a 210 x 210 with room for a squirt around

    The Creality Ender 3 definition file ("...\resources\creality_ender3.def.json") includes those "disallowed areas" for the metal clips that hold down the glass build surface. You could go into the definition file and delete those areas, but the easiest fix is to install an Ender 3 Pro which doesn't have those areas but is otherwise identical to the Ender 3 definition.

    Thanks GregValian

    The disallowed area explain the issue

    BTW the json file is at .../Ultimaker-Cura.app/Contents/Resources/share/cura/resources/definitions

    I went back and look in my older laptop and indeed was using:  Ender 3 Pro, the v2 was not listed in Cura 5.0,

    only Ender 3, and that one already had those disallowed area

    That brings another question

    I did try to copy and paste start and stop G-code in machine setting window

    but copy and paste does not work

    I can type and delete directly in the window, that works, not copy and paste , not with a right click, not with the global menu

    I am saw a demo done on a Window pc where that works

    Is that normal on Mac, intel or arm, it is the same?

    Any way, now I can do it in the json file, so no biggy

    Thanks for the help

    Remember to save your version of the JSON file somewhere.  If you update Cura the stock version could over-rule it.

    I do the same thing with my installation (alter the JSON files, Cura build plate file for my E3Pro, etc.).

     

    You have to use keyboard commands to cut, copy, paste in the Machine Settings dialog (for example:  CTRL+V works for Paste on a Windows computer).

    As far as I know it's been like that on Windows computers for numerous versions.  It might have something to do with the Qt controls used by Python for dialogs and controls, or maybe the developers work in Linux and missed something.

    Hey @jacprint,


    If I change your Build Plate Adhesion Type to None you can reach 216x216x11

    image.thumb.png.2d130d7555d1904d53259c6091cf1590.png

     

    That way you'll only see the single greyed out areas that have to do with the clips.

    Hope this helps 🙏

      • 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
