Inconsistent movement in print

Recommended Posts

Posted · Inconsistent movement in print


We hope someone here can provide some advice about the movement in the printing process.

Without adjusting anything, we have noticed that with every print, the head would start in one speed for maybe 5mm of height, then decide to slow down for another 5mm, then change to the faster speed again, and will alternate between the two speeds until it finishes.

We have guessed that it might have something to do with Print Acceleration and Jerk settings, however, after adjusting those setting in Cura, there has been no noticeable difference.

If someone here would have some insight, we would appreciate it very much!

    does it happen with all models you are printing?

    Maybe the model is shaped in such a way that a layer falls short of the minimal layer time and the printer slows down.

    There are many different jerk and acceleration settings which are hidden. Try to display them all, and maybe you can get the behavior you expect.

    But of course I advise to stick to all default settings, cause usually these are really good
