S5 flow rate & printing blobs in infill

[jantograaf 0]

Two questions:

 

1: Is it normal that for almost every material (PLA, ToughPLA, ASA, ABS) the flow rate has to be changed from 100% to 95% in order to achieve decent layers? 

2: When printing with FilRight ASA Engineering filament, I tried using the quarter cubic infill. However, during the print, I can see 'blobs' of material showing up along the infill lines. See attached pictures. Am I printing too fast? I have attached the CURA profile that is currently in use for this print.

This happens to me also with PLA and ABS prints on other printers. When your nozzle travels arroud some little amount of material can flow out and create this blobs. As far As I know it is nothing that affects the print qualité or the physical properties of your print.

@Curven so this is actually some kind of 'stringing' that attaches to the infill lines on travel moves?

[Curven 28]

As far as I know, yes.

It is normal that you can see this in the infill, because infill is printed faster (normally) and there is no retract when traveling within infill, because it doesn't matter if there are strings or not.

Hi

 

The issue is not unique to the S5. The UM3's (and I suspect the 2 as well) also do the same thing. As long as you are using standard Cura profiles, you will get a bit of "extra" infill. This is the desired thing vs too little infill. As mentioned above, they can print faster if they do it this way.
