Fine tuning line width for small rectangular pyramids

· Fine tuning line width for small rectangular pyramids
Could you post images (screendumps) of the design in Cura, and photos of the results? The photos with ruler, so we can see the dimensions.
I haven't printed with nylon yet, but there could be other things involved, such as insufficient cooling in a tiny model, so the model can't solidify. Or overextrusion due to slowing down in corners, when the internal pressure can't immediately be released, etc.
For PLA, printing slow and cool usually helps. And printing a dummy tower next to very small prints, so the nozzle is away from the model, allowing it to cool, and so that printing-time per layer is equal for all layers.
As said, this works for PLA and PET. But I don't know if it also applies to nylon (if too cool, you get poor layer bonding).
But of course, it could be something else too.
Below: a few images of the dummies: the basic concept, and a real model.

Thank you. Your comment about slowing down in corners resonates - these are small teeth and corners are exactly where things are getting messy.
I'll try to explore ways to change how that path is laid down. If it was CNC I would know how to change that toolpath, but I don't have that skill or knowledge (yet) here. Fortunately, there are some smart people to ask here ?
For a dummy tower, is that simply a matter of creating a separate STL and importing it to Cura, or can I do that within Cura itself?
Thanks again!

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
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.
