    Ender 3 Build Space usage

    Hello there,
    I?m new to 3D printing but able to resolve most problems myself.
    Recently I encountered a problem with a very large piece that almost uses the whole build surface. While printing with a brim I noticed that the round piece got cut of at the edges of the build surface. The printer refused to print a curve, just ignored the G-Code and printed a straight line following the shape of the build surface.
    Cura didn?t show any of this and there was a good min 1.5 cm headroom to all edges.

    Is there a set value of boundaries in the Marlin firmware?

    Didn?t find a solution on google or the search function in this forum.

    Any help is appreciated.

    Yes there are boundaries.
    In Marlin, and in Cura. Both should be set for the build area for your 3D Printer.

    Found the section in Marlin (vanilla 1.1.9) under config.h
    Strangely it was set at 220 instead of the 235 of the printer tough Ender 3 was configurated.
    235 troughs out an error with my BLTouch being out of the probe range, 230 works just fine.
    Thank you now cura and the printer are uniform and 5 mm lost I can count as a safety range.

    I avoid filling the entire build plate if possible. To easy for things to go wrong IMO
