Match your thickest perimeter from your slicer settings (internal/external). 🛈 Includes first layer. 🛈 Use your external perimeter speed from your slicer settings - if it's reasonably fast (>60mm/s). If the results are hard to read, try a faster speed. 🛈 Your MAX accel will be used if you don't set this.

Use a slicer to generate g-code for the large hollow square found in docs/prints/square_tower.stl. Use a high speed (eg, 100mm/s), zero infill, and a coarse layer height (the layer height should be around 75% of the nozzle diameter). Make sure any "dynamic acceleration control" and "scarf joint" seams are disabled in the slicer.

Adjust your printer's Pressure Advance (PA) setting according to the value that produced the best results in your test. You can run the test again with more accurate intervals for better results.

One thing to check is your extruder backlash. This is a common cause, but only one of many! Make sure there is no “dead zone” when reversing extruder directions by hand. Make sure nothing is misaligned or loose. On bowden extruders, ensure that your tube fittings have minimal/no play.
