Dimensions print in Cura ok, but when printed 5mm bigger


Recommended Posts

Posted · Dimensions print in Cura ok, but when printed 5mm bigger



All of a sudden I have this weird problem. When I slice a model in Cura (5.3.0 + Xmas), the dimensions are ok and scaling is 100%. But when I print on my Ender 5 via Octoprint and Pi4 the actual printed model is 5mm bigger. Last time I printed (week ago) it was just fine.

Maybe someone knows where to look? 



- Scale is 100% and dimensions are ok in Cura when sliced

- converted in mm and sliced in mm

- when printed overall design is 5mm bigger

- All is tightened and checked on printer (Steps are correct)

- Printing with Cura 530 + Xmas and send to printer with Pi4 and octoprint.

    There's a bunch of settings in Cura that could potentially affect this. If you could provide the Cura project file (.3mf, go to File > Save Project in Cura) that would be great.


    Also a couple of things:

    • Have you tried a more recent version of Cura? The version you're using is nearly 10 months old and isn't a stable release to begin with.
    • Have you looked at the g-code to see if the code produced is the correct size?
    • Have you tried printing directly from the printer (using an SD card)?
    • Have you updated the software on your Pi (especially Octoprint) in the last week? There was a new version of Octoprint released yesterday.
    • Have you updated your printer's firmware recently?
