I am having trouble with a Lift switch error on the Ultimaker S5. It is currently up to date on the most current firmware which is 8.1.1. Basically any time I do the lift switch calibration it looks as if it works. But as soon as I start a print and the print head moves over to flip the switch it misses just barely. I've already power cycled the machine, and as I stated I updated the firmware to the most current version. I also made sure that the belts were tight and not loose. Does anyone have any ideas to what could be causing this? I will include 2 short video clips so you can see what is happening. The lift switch video is how it looks when I calibrate and it. In the print start video you can see what the problem is when it moves to flip the switch.

    Is your #2 PrintCore fully inserted correctly? it should be lit up during these tests I think? You should be able to visually confirm the nozzle moving up and down when you toggle the lift switch by hand.

    I have removed both cores, and reinserted them to be sure. The nozzle does move up and down by hand. It basically just seems like it doesn't save the calibration. During calibration it works fine, but as soon as I start a print it moved over to flip the switch and misses.

    As far as I can see you performed the calibration just fine. The behavior in the second movieclip is normal. At the beginning of the printjob the printer makes no assumptions on the position of the lift switch. The move that you see is to make sure the switch of towards the front of the printhead.

    What error do you run into when you leave the printer to finish this printjob?

    The first probe is supposed to be done with the right nozzle, and the second probe with the left core. 
    Then the grid probing should be done with the left nozzle. 

    I think the best thing you can do is create a support ticket on our website

    I would check your Y Limit Switch, its just out of view on both of the videos so I cant tell.

     

    But generally when the lift switch is not being toggled properly its a sigh that your limit switch is damaged.

    Y0pher, did you get this fixed? I am having a similar issue and can't fix it... (Email julia @ makergirl . us if you feel inclined to help me!). When I try to manually move the lift switch it doesnt move either so i cant figure out how to fix this. I also have the most updated software!

    If you cant manually move the lift switch, that generally means the head was not reassembled properly.

    After contacting support we discovered the problem was actually with the axes being unaligned. When looking down on top of the printer the Y axe was slightly at an angle. After adjusting it is now hitting the lift switch as it should. I'll include the link to the instructions they sent me.

      • 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
