First tighten the screws a lot. maybe half way tightened between max and min.

Then make sure the z limit switch is clear of debris. With power off pull the z bed up high and insert something into the z switch limit hole. Like a small screw driver and make sure you can hear the limit switch click. This is probably not the problem but good to check. Sometimes bits of plastic get in there.

Now run the procedure and skip over the first part moving 1mm above in 3 spots. That's just a safety thing. Then when it goes to the back - the part most people don't realize - is that you have to rotate the wheel to get it to touching your paper between nozzle and glass.

The default air gap between the aluminium base and the bottom of the heater PCB should be about 14mm. It's fairly important to not stray too too far from this as it can cause issues with the automatic bed levelling.

What I'm guessing is that you are using the screw in the back to adjust the bed during the first step? This is wrong, you should be rotating the menu knob to adjust the bed height for the back position. You only use the screws for the front two positions, not the back, always use the menu knob for that position.

    my menu knob does not move the bed, should i take a video of everything the printer does and i do to it?

    That sounds like the problem. Could you go through the whole procedure very fast - just continuing several times until you get to the problem menu please? And film the begining where it homes the bed also.

    1) I'm wondering if you need to proceed one more time through the menu before you can move the bed or

    2) Something is wrong with homing the Z or

    3) Other.

    Your menu knob should only move the bed when adjusting the back rear point. For the front adjustments, you should be using the 2 screws on the underside of the bed in the front corners.

    When you first start the leveling, it will ask you to adjust the bed up/down using the wheel on the front of the machine. After this, itll switch to fine adjustment asking you to use the physical bed screws.

    I went through this last night, ended up doing initial adjustment by manually measuring the aluminum bed floor to the bottom of the heated plate to be as close to 14mm as I could get using a small metal ruler thing, otherwise I think it'd be hard to know where that 14mm would be without measuring..

    Then ran bed leveling and did fine adjustment with the screws just to level it out, this way getting the bed height close to the preferred height Robert mentioned.

    I had the same problem after dismantling the bed to remove material that had gotten underneath during a failed print.

    The solution turned out to be adjusting the rear know before starting the leveling process. I had tightened it town over half way. To fix the problem I had to loosen it back off a pretty good bit. This raises the back of the bed to allow the front knobs to be looser. If the back knob is too tight, then the back of the bed is lower, and you can't tighten the front ones far enough to get bed down.

    Also, the menu knob only works during discrete steps in the process. It will only adjust the rear position of the bed. The corner screws must be used adjust the front of the bed.

    Hope this helps.

    We should stop replying in this thread.

    The guy made 2 posts a month ago and never followed up. I don't think he ever came back and read any of the replies.

      • 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.
