Head crash at end of print

Hi,

 

At the end of a print, our S5 paused for a brief period and then raised the print bed to about 10mm from its maximum and began its material purge (we are connected to a material station). This caused the print head to crash into the print. Fortunately, the geometry of the allowed the head to slide off but this was shear luck. We are using Cura 4.5 and S5 has latest drivers.

    We had an incident not long after we bought our 5S that the print head crashed and pushed the glass free of the clamps and scratched the aluminum platter below. It happened on the weekend during a long print. When we left the factory on Friday, it was operating completely normal.  We think it was due to a power spike/fluctation surge as our facility is in a rural area.  The hot end actually came in contact with the aluminum under the glass and put a scratch into it. In order to do this it pushed the 3D print to the side and overcame the resistance of the bed clamps. On Monday we found the glass pushed to the side. Call it impossible, but it happened. Since that time our right/left belt is loose.  It must have tried to self-correctedsomehow because it proceeded to print the rest of the 3D print as a birds nest of material.

     

    A major design flaw of the 5S is the inabiltiy to adjust belt tension on the main belts (you can adjust belt tension from the drive motor to axis, but that is only 1/2 the tension required. Ultimaker should take note of the cheap consumer printers like Creality where you can adjust belt tension easily. We like  the Ultimaker overall but just pointing out something to improve in the future.

    I disagree. The Ultimaker printers are -at least since the UM2- equipped with an automatic belt tensioner for the long belts, which is integrated in the sliding blocks. If the belt gets loose at the opposite side (lower at front/back belt, higher at side belts), there is an easy way to tighten them again, as shown in the following video, provided by @fbrc8-erin:

    I had the same issue yesterday night with an S3. I thought that I didn’t lock the bed, but that isn’t something that I would forget.

    the entire nozzle and head was filled with pla. Luckily I could remove it with a heated modelling tool, no damage to the head but the print core is bust

    I had the exact same thing happen for the first time the other day, same setup as well.  Hopefully this will get resolved soon.

      • 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
