Posted · [UM2] Problem printing a good flat surface

Hi everyone!

I've been having this problem for a while and can't figure it out:

I though it might be the short belts so i tightened them put sadly it didn't improve the situation! The bed is also levelled nicely as it always only seems to be an issue on diagonal flat surfaces. Could it be slicer related?

Hopefully, someone has some ideas!

Regards

Max

    Hi Max,

    This looks like you have to much play in the linear bearing(s) in the extruder unit.

    To inspect this, (the printer do not have to be switched on) hold the extruder from above with your left hand to prevent it move, then use your right hand from below grab the lo part of the extruder without touching the wiring on the reverse side of it. Now try to move the extruder at this place forward/aft for the Y axis to see if there is any play. Do the same thing right/left (the X axis).

    If there is to much play here, you will see clear opening in first layers..

    This is a test to be repeated in different positions for the extruder, as such play can be related to spesific positions..

    OK. Good Luck.

    Thanks

    Torgeir.

    Edit: The four sliding bearing on the 4 X 8 mm shafts may also cause such error, but same procedure will cover those as well. For those bearing (inside each of the four black sliding blocks), you can also feel play when moving those block (carefully) up and down, much forces must not be used 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
