Sometime I print multiple things after each other, same color of PLA and nothing changes.

But every single time the printer makes the "line" at the bottom of the bed. The printer head is at 2 mm height and it makes a thick line all across the width of the board. But why?

Is it possible to remove this somewhere in the code or in Cura settings?


I always have a brim of 4mm that is printed and my bed is autoleveling before each print so it seems a bit waste to print this when printing 10 pieces a day, I do not need these test lines between every single object.


How to remove it?

    The purge line(s) are in the StartUp G-Code.  Click on Settings / Printer then down at the bottom is Manage Printers and then click on Machine Settings.  In the lower left window is the startup gcode.  The purge lines may be noted like...

    G1 X1.0 Y20 Z0.3 F5000.0 ; Move

    G1 X1.0 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line


    if you put a semi-colon in front of the lines they will be comments and the printer won't pay attention.

    ;G1 X1.0 Y20 Z0.3 F5000.0 ; Move

    ;G1 X1.0 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line

    Thank you friend!


    I am new to this and am not understanding much code even if I look for solutions. What I have is this;



    G1 Z15 F300




    M104 S215

    M140 S70

    G92 E0

    M109 S215


    G0 X10 Y20 F6000

    G1 Z0.8

    G1 F300 X200 E40

    G1 F1200 Z2

    G92 E0




    I can only guess that the line is this part;

    G0 X10 Y20 F6000

    G1 Z0.8

    G1 F300 X200 E40

    G1 F1200 Z2


    But I am not sure.

    This one first sets the Z height and then extrudes to X200

    ;G0 X10 Y20 F6000

    ;G1 Z0.8

    ;G1 F300 X200 E40

    G1 F1200 Z2  ;This one is OK as it just raises the Z.


    The line that has the "E" in it is the extrusion line.  The Startup gcode sets your machine up to print.  The Gcode list @ MarlinFW.org is the full listing of the G and M commands.  You should look up the ones you have there so you understand what is going on and the order it is happening.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
