| Dec 26, 2018 at 22:42 | comment | added | Emile D. | @Trish: You are right. I just noticed that the heatbreak was spinning with the heater block, not because it was like this by design, but because the screw was not completely closed. The nozzle was not pushed on heatbreak, thus causing a poor conduction of the molten filament, leading to the PLA finding a way between the heat block and the nozzle. Thanks! (I would love to upvote your comment.) | |
| Dec 23, 2018 at 23:50 | comment | added | Trish | @EmileD. actually, your nozzle is leaking because the nozzle's top is not closing up against the heatbreak or the liner in it. | |
| Dec 23, 2018 at 23:12 | comment | added | Emile D. | Nevermind, I think I have an idea why I have dripping. The nozzle gets wrapped around by plastic during the printing. I guess the pressure makes the PLA turn around the filet of the nozzle, and makes its way to the outside. I was indeed surprised to see PLA on the filet each time I remove the nozzle, and would be a perfect explanations to the molten/burned PLA. | |
| Dec 23, 2018 at 22:59 | comment | added | Emile D. | I add an information there: during the last cleaning, I noticed that inside the nozzle, the plastic was hollow. I wonder the setting that withdraw a bit the filament, to avoid the strings everywhere, was not stretching a bit the plastic unequally, and making the layer printing less predictable. | |
| Dec 23, 2018 at 22:41 | comment | added | Emile D. | @Trish Hm, I am still interested to have other information that could improve my prints! :) What do you mean by my hotend is not sealed? I sadly can't find a good explanation of why I have drippings. Mostly because I can't see any other holes where the dripping could come from, thus I have to assume that it comes from the nozzle... | |
| Dec 23, 2018 at 22:37 | comment | added | Trish | @EmileD. that sounds like the hotend is not sealed... a different question though | |
| Dec 23, 2018 at 20:32 | comment | added | Emile D. | @Trish Indeed, I think lowering a bit the print speed did help. But I cleaned the nosel several times. The last time by putting it in boiling water then cleaning a bit by end. It was not enough to remove the big chunks that I have sometimes. It is quite like I have molten PLA accumulating, burning a bit, and then dripping down... | |
| Dec 23, 2018 at 11:12 | comment | added | Trish | @EmileD. As 0scar said, check your nozzle. Another item that can cause the front denting in is too high print speed - I find that 60 is the highest that I want to use for visible walls. | |
| Dec 23, 2018 at 6:21 | comment | added | 0scar♦ | @EmileD.e The burned filament could well be caused by your high temperature sessions, please clean the nozzle. How m y perimeters has the model? | |
| Dec 23, 2018 at 1:04 | comment | added | Emile D. | @Oscar. Sorry for the delay. I was busy this week. The few prints I did failed, mostly because the extruder jammed. I was trying to tackle that problem. I just got a new print around 200°C that worked, but the dent is still there. And what I got from an even lower temperature still had the dent. But there were less rogue strings everywhere. | |

| Dec 17, 2018 at 4:19 | comment | added | Trish | @EmileD. you print far too hot. I print PLA at most at 200 | |
| Dec 17, 2018 at 1:02 | comment | added | Emile D. | Thank you a lot for the answer. May I ask some questions related to the temperature? What is the cooling fan doing exactly? (I was seeing it as a way to have a better precision of temperature control). And what are the trade-off with the hotend temperature? (and even hotbed temperature?) | |
