UM3 Jerking? Overshooting? I have a problem...

Recommended Posts

Posted · UM3 Jerking? Overshooting? I have a problem...


I have the problem you see in the picture

Those "jerkings", "Jumps", are afecting not only the looks, but the final size of the printing, and making it very hard to create components with the right tolerance. 

Even on square pieces, when it gets to the corners I get this kind of "niple". I don't get a straight angle.

In this circles you can see, that every side, when ends, instead of moving smooth to the next segment/side, it has a jerk/overshooting like finishing.

I have checked belts and they seem to be tight.

Might be there any setting that I should look at?, or is it maybe some specific hardware I should be looking at?

Any good suggestion??

    Jason, thank you for your reply.

    I am trying to figure out is reason is hardware or settings, but I can't really see anything clearly in the mechanism to blame hardware, unless I am missing something.

    Here are the settings I am using.

    Nozzle is 0.4mm

    About Jerk speed, I can't see where there is the field to fill numbers, except, enable or disable Jerk control.
