My UM2 X/Y is skipping steps at high speeds! Thought that was licked long ago?

Posted · My UM2 X/Y is skipping steps at high speeds! Thought that was licked long ago?

I haven't printed in a while, as been busy with other projects, but I'm noticing that my UM2 is skipping steps on both the X/Y axis when doing a long "jump" at high speed. So X and Y starting positions on subsequent layers are off by about 1mm on each axis, causing a leaning print in both x+y. All belts are super tight. All pulleys are super tight. All axis are straight and lubed. What gives? Naturally, printing at normal speed results in no issues.

Now I've also got a totally tweaked/modded UM original which is a beast of printer and can print flawlessly at super high speeds. However, it does have much bigger motors than the UM2

I'm I not remembering something? I thought the UM2 was engineered to print super fast and flawlessly? Was I imagining this?

Thoughts?

    If you *tune* the speed up to 150%, then you not only increase printing speed, but also traveling speed (which is usually much higher than printing speed). If traveling speed would for example have been set to 200mm/s, then that would become 300mm/s after tuning, which might be higher than the maximum the stepper motors can handle without skipping. Could that be the cause?

    When playing around with tuning speed up very high, just to see what would happen to my extrusion, I experienced something similar.

    I would suggest you try setting the printing speed at a desired high value in Cura (or whatever slicer you use), but without increasing traveling speed above a safe maximum. See if that works?

    That's a good point, Geert!

    I will remember that and revisit settings using the new Cura.

    Thanks for the insight!

      • 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
