Ultimaker3 E-steps calibration

Posted · Ultimaker3 E-steps calibration

Hi,

I repaired an old ultimaker3 in my workplace, everything works fine excepts it's under extruding so much. I tried to calibrate in ssh way (I use PUTTY), I found some code from topics before, but I'm not that experienced coding in this way.

How can I  find out what is the steps/mm value of the motor now? Then how can I set it with coding?

And I'm also confused, with what kind of circumstance should I calibrate? Hot/cold, with/without nozzle, with/without tube, I've read a lot of variations.

 

Thanks,

K

    Unless you changed the hardware to non-standard parts, you do not need to calibrate the e-steps. The e-steps are a function of how many steps per rotation the stepper motors are, and the gearing of the feeder. If the printer is consistently underextruding, something else is going wrong. For example the feeder could be slipping, or skipping steps. You should not fix that with the e-steps configuration.

     

    Do you know that the Ultimaker 3, like all other Ultimaker printers, is made to use 2.85 mm filament (as opposed to 1.75 mm filament)?

      • 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
