Extruder goes to far from platform


Recommended Posts

Posted · Extruder goes to far from platform

I've been having a problem, after some successful prints. I've leveled the bed multiple times, but every time I try to print, the head goes to home, moves, and winds up about 0.5 cm too far from the print bead when it starts to print. I've adjusted the endstop multiple times, same with the height of the build area.

Any thoughts?

    Wow! I have never seen that before. And I've seen a lot.

    I think your Z stepper is slipping somehow.

    Is the z screw firmly seated into the Z coupler at the bottom of the z screw? Look at the first 2 pictures in this post:


    The first picture shows *good* z screw insertion. The second picture shows *bad* z screw insertion (sticking out).

    More likely you are slipping on the motor shaft. Try tightening that bottom screw quite a bit. The set screw that connects the coupler to the stepper motor. Tighten it much more than you think it needs to be.

    You can test things by homing, and then moving Z up and down by 10mm. You can do this with the ulticontroller or with the Cura print window. See if the screw is truly moving up and down by 10mm. If you install pronterface (it is free) you can adjust acceleration settings for the Z axis. Maybe you have too much friction in the z screw for the default acceleration. Although if it were me I would fix the friction and leave the z-acceleration alone. If you *do* change the z acceleration remember you have to save it to eeprom or you will lose that value the next time you power off the Ultimaker.

      • 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
