Advise to slow down is no better then increasing the flow by 150% for 1st layer.
Not only i would have to use plugins to tweak 1st layer but it will also mess up 1st layer dimensions. It will also make 1st layer fill too much causing the nozzle get filament allover it on the next layer, unless i set 2nd layer to 50% and 3rd back to 100% to balance things out.
Ridiculous !
Yes, ridiculous. Ridiculous that you think that.
Naturally Cura adjusts all offsets and line distances if you change the line width for the first layer. So you do not need to adjust anything else, as it will put down wider lines but at a larger distance from each-other.
But I guess you assume I'm an idiot.
Also your math does not add up, if Cura was not as smart as it is. The first layer is thicker, so 150% of 0.3mm layer, next layer is most likely 0.2 for you, so that would mean 50% * (0.3/0.2) = 75% more material which would have ended up in the 2nd layer. So you would have to put the flow of the 2nd layer to 25%.
However, this is not the case, so I'll ignore that piece of flawed logic right there.
Absolutely have no clue what problem you talking about with the second video. It printed the layer perfectly. Skirt has some oozing but that has nothing to do with the layer print.
It's all down to nozzle shape. The way your nozzle is shaped greatly increases the curling up effect. Which you see as a "blob" at the start of the line. That's why you see no Ultimaker users complaining, as they have the "flat end" nozzle which forces the material more downwards into the tape, instead of giving it room to curl upwards.
I am more than happy with a workaround.. But using Hairspray isn't an option for me, as removing the parts is already difficult enough... I don't think my problem is adhesion.. Its just that the perimeters are not 'closed' and the open ends have 'blobs' which catch on the next pass.. Thats why I believe that doing a few laps for each perimeter would be a good solution.
Try the "initial line width" setting that I suggested above. Most likely it will make a difference. Changing the initial layer speed (which is tuned for an Ultimaker by default) could also help.
Your problem isn't the end adhesion. It's the adhesion while the material is still hot. That's a whole different set of mechanics happening right there.

Tony.. Please keep debating this.. As you know I share the same issue/concerns and I don't have the knowledge or words to express my views.. I just know that I see exactly the same issue as you have demonstrated and its driving me nuts.

But I don't believe this is easy to fix and dont' expect anything to happen in CURA, so workaround is my only option!
