I've have observed that when the printer is finishing a layer, the flow of plastic through the nozzle starts fading out as it comes closer to the point of layer change.
As an example, let's say that I'm printing the first layer of a cube. The nozzle first prints the perimeters ok. Then it begins to print the inner part, beginning from one corner and finishing on the opposite one. As the nozzle comes closer to the finishing corner, the flow of plastic diminishes, resulting in the lines of the filament to touching each other.
Maybe it's not a big deal, but it's annoying because it's stopping the part of having a very nice first layer and finish.
My setup is:
- Anet A6 running Marlin 1.1.8
- Bed auto leveling before each print
- Slic3r Prusa Edition, latest release (as of 20 January 2018)
- PETG from Das Filament
I tried disabling all "retract" settings but the issue persists.
I'm beginning to think that this could be a software bug (Slic3r), but before I submit it to GitHub, I'd like to be sure.
Any opinion is welcome!
