Big lip on print. Not sure what to do


Recommended Posts

Posted · Big lip on print. Not sure what to do

Hi, first post and first time using the Cura software. I printed a project for my son last night. It was a desk with drawers and he broke all the pieces out into separate components. It looks something like this. 




I selected support and adhesion, which gave me something like this once sliced and previewed. 




But when it printed everything seemed to have a misplaced bottom layer, where there was a big lip sticking out at the front and a gap at the back, as if the bottom layer had slipped. 




Is this meant to happen and I'm supposed to remove this layer, or have I done something wrong? Apologies for the basic nature of the question. Like I say, it's my first time working with this and I'm learning as I go. Oh, and the printer is a Geeetech A20M.


Many thanks for reading.

    This is extremely common.  It's a problem with your printer.  First you need to know if it slipped in X or Y.  Then concentrate only on that axis.  I'm guessing you have one of those printers where the bed moves in Y - it's most likely that axis if you do.


    So then something slipped.  Some pulley on the stepper or pulley on a belt.  Those pulleys have a tiny set screw.  Tighten the hell out of that screw.  I mean so tight that if you use an allen wrench and hold the short end of the L in your fingers it hurts.  A lot.  the shaft should twist slightly.  That tight.  Then try printing again.

    The end cabinets (that I suppose the drawers go into) might be able to be rotated open end up so they don't need support on the inside. 


    When printing things with large flats on the build plate you can often get by with a skirt instead of using brims.  They use less material and don't need to be trimmed off while still getting the flow going.  So I would do the legs as a separate print with a brim (so they don't fall over), and the rest of the stuff with just a skirt.

      • 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
