Tall objects

I am having problems with printing tall objects. Like this for example
https://www.thingiverse.com/download:722296

When I try to print the poles (150mm high) at some point everything becomes a stringy mess. I am using a brim to make sure that the parts are securely attached to the base. No issues there.
I also removed the spool from the top of the printer (in case it created more vibrations). Also slowed down to 50% in order to have even less vibrations.
Slicer used SlicerPE (Prusa PLA filament, infill 15%, brim selected and supports on base plate only) using the 0.2 QUALITY setting and using the default 0.4 nozzle.
Filament used Prusa (not prusament) PLA.
The best I got was 120mm before the stringy mess started.
Any recommendations at what to do?

Re: Tall objects

A photo of the mess would help.

At this point, guessing the the part coming loose from the bed?

Thanks for the response. The part was still fixed to the bed....looked as if the head crashed into the object or maybe a layer did not join with the previous...unfortunately did not take a photo of the mess.

Re: Tall objects

Tall parts can partially detach, especially if a brim is used, and look attached; they wiggle without much force and eventually fail. If a part is moving under the extruder, it's come loose or the part is too weak for the height and needs lateral supports.

Thought a brim would make the part(s) attach better. So next time no brim.....How do I add lateral supports? Is there a setting in SlicerPE?

Re: Tall objects

Brims do help keep parts attached: but they don't help much if the bed isn't clean, or if the part has a very small bed to height ratio. Printing a pencil vertically is problematic.

Slic3r PE doesn't have the ability to create lateral supports (that I know of).

Lateral supports are typically designed in when creating the part in your CAD tool.
