Ok, so you are having multiple problems, lets break it down: At the speed you are pushing, it would not be weird to have the Y belt slipping around. Also inertia comes into play, so please, dont do that. What you are mentioning about the filament going out a bit, also makes sense. You are exceeding the max volumetric flowrate for the ender 3. I would ...


Have a look at Chisel infills there are very strength optimised, limitation is currently that they must be single line width, but multiple-lines thick infill will be supported soon. After that, it's very simple, basically setting double corrugated infill with corrugation size 1 for your rectangle model.


TL;DR: Don't do that. Detailed answer: You need motion limit parameters that actually make physical sense, and firmware capable of executing a motion plan according to them. Your jerk and acceleration settings absolutely don't. Marlin's whole implementation of jerk is wacky (note: modern Marlin versions don't even use it but an alternative they call "...


Yes you can! To have stronger prints you would have to choose the correct direction of filament deposition paths/traces. This answer demonstrates changing the direction of the filament path in Ultimaker Cura slicer. To do this, it requires some tinkering of your model and choosing the correct slicer parameters (decimals aren't allowed in changing the ...


The way I get rid of voids, like your triangular shaped voids the slicing program interprets as fill area, is to increase the number of vertical/perimeter shells (the shells on the side).


If on even layers, the routing is in one direction and on odd layers, the routing is the opposite diagonal, you'll have a much weaker structure, as there will be no material after the crossing point. Addressing that aspect, one could consider that the design is implemented in such a way that the nozzle creates the odd layer continuously from one corner to ...
