Bed print area restriction


Recommended Posts

Posted · Bed print area restriction

I'm using Cura 5.2.1 with a Creality Ender 3 Neo printer. I've replaced the original bed with a magnetic PEI plate that does not require clips.

The bed size is stated as 235 x 235 and i'm trying to print a circular disc which is 220mm wide total. Cura has a thin grey area at the front of the plate which does not allow me to slice unless i reduce the disc size down to around 213mm. 

I've found a link that suggests editing the json file and removing the restrictions on printable area but when i try and save the edited file it gives me permission issues which i cannot seem to resolve.

Is there a simple fix for this...any help appreciated

    Hey @Deepblue12,


    Welcome to the Ultimaker Community 🎉


    Before you change your Printer Definitions there is something else you can try.

    There are a number of settings that influence your build volume. 
    You can change this for your specific printjob without influencing any of your future printjobs by permantly changing your configuration!


    • Build plate adhesion, You can reduce the brim size, or set the adhesion type to None to get a lot of space back
    • Travel avoid distance, is you reduce this to 0 you should also get some space back but the nozzle might leave some residu on your print
    • Support horizontal expansion, if you have support enabled horizontal expansion helps with printing on top of the support but influences the space you have to print


    You can read more about them here.

      • 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
