Strings between parts.

[DrLuigi]

Just done the same part again, Same settings, Except i did my temp to 205 as i found that the plastic didnt went through the nozzle that easily at 190.

I find these results even better imo,

I didnt clean up the strings when making pics btw.

What are your print settings for this job in Cura?

Can you send me the link to this part, I'll try printing it and take a picture.

Well, It was at 0.2 layer height, 205c hotend, 13mm/s retraction speed 4 retracted
Speed of about 40mm/s (printing speed).

I changed a few settings while getting another print ready, But i have it all in my head, if you need something just ask, I think i already told you everything thats necassary


Edit:
Just made the hollow pyramid again,

Not that great, but not bad either tbh.
I do think i must decrease my time on how long a layer minimum should take, wich is 5 for me at the moment,
I think the nozzle is warming up the previous layer to much wich causes that round shape at the top.

It is a difficult part to print, the first one was the blue one, not bad, then the purple, don't know what happened there, last one is red and the best one I find.

I used all the same settings for all 3 except for the temperature because they are all from different manufacturer and melt at different temperatures, I found those by trial and error. I've included my settings.

100mm/s retraction? Thats rather fast,

What printer are you using?

And ye the purple one is very akward,

The others are almost like mine, Ive gotta say for such a simple print, it is rather hard to print it out nicely :P

[Sysgen]

100 just means go as fast as you can which is not really fast. I have a Prusa i3. These little motors don't turn fast at all.

[DrLuigi]

well 13 seems to be the max for me here, 780mm/min in prontrface tells me the same thing lol :P

Oh well, I guess stringing is now pretty good, after some small strings. guess you can only lose those with another hotend or ABS perhaps. as PLA oozes more.

[Sysgen]

One thing I notice though, I do not have stringing like you do and I have a jhead also.

Unless we can all use the same manufacturer and batch of filament while also accurately measuring hot end temperatures, we'll never have a definitive solution to zero stringing. Too many factors to consider...
