also fast movements tend to drag model off side or off model completely. and I find very tiny objects near imposible to print as there are limits and details get lost also. another trick with tiny prints is do multiples so it dont stay on 1 so long. like load a dozen of the object and arange them on build plate with gaps to keep hot end away from each object. even check the box for 'avoid crossing perimeters". makes longer print time but less waste. it also makes for very busy print head motors so watch over heating mosfets? etc

In some slicers you can also set a minimum layer time. This really helps when you print a large object that has some small layers.

When printing items like this you need to print more than one or print something else at the same time. The head is staying in the same area too long so the overall temp stays at the melting point for several layer. That results in the layers just smooshing and moving around on top of each other.

Simple yet incredibly effective. Was having issues trying to print small figurines, read this and tried printing two at the same time and they came out great. Very effective tip!

Serious question here... reduce it by or to 20?
He means to 20mm/s. Smaller parts need to be printed slower so previous layers have more time to cool.

Thats correct ! Sorry that I wasn't clear. In slicer, you can set the speed in some parts of the print (like perimeters, infill etc). When you have small printins (I mean small layers) just set the printing speed to 20 mm/sec, so the ABS has time to cool off and hardens.

+1. put a skirt of height 999, 1 mm away from the object. if this isn't enough, move it out several more mm.

Can someone please tell me what is causing this? I cleared a jam and now this is happening. Z axis calibration was fine.
