Press J to jump to the feed. So, my thought process is the following: since I run at lesser temperature, there is still potential for the heating block to provide more heat and I need a longer nozzle to accumulate more heat and provide more surface area for transfer to the fillament (PLA), to speed up the melting of the plastic inside the nozzle (which seems to be the bottleneck). Making statements based on opinion; back them up with references or personal experience. Set the flow percentage, which applies to all E moves added to the planner. Out of curiosity I updated flow to 157% and now I am actually getting the correct wall thickness on the thin walled cube, but the XYZ cube I printed after that is terribly over-extruded. Switch back to cura 4.6. Use MathJax to format equations. 4.7 is messed up. Intuition about why gravity is inversely proportional to exactly square of distance between objects.
