Yesterday i tried to do the underextrusion test from iluminarti... It was a total failure!!!!! btw, i like your methof of feeding the machine, but what happen when you Need like say 45 meter Filament? i ordered an Olson block yesterday,... and i think it can be my nozzle, because, i was printing a lot of bronzefill and Xt the las couple of days... do you have a link to the RIGHT atomic Method? maybe i was doing it wrong.

Hey Cloack Fiend, the last Thing i printed was yesterday and i indeen showed you my Progress... today, im going to print smth small and then see what happens... ill try the ultimaker Robot as you told me...

well i think it has smth to do with my nozzle... its has been printing like 1500 hours...

so whats The problem!? im getting really annoyed... because i don't know what else to do...

and the motors are quite warm...

well, its summer here...

but at least doesn't seems like underextrussion

[media=2762][/media] and the walls sucks too

the top layers still sucks...

@Didierklein: Thanks for your advice, im using the last Version of Cura (15.04) with other Colors i have similar results, but a Little bit better.... whats the good Thing about Roberts Feeder?

and bowden tube i've tried with two different (also i bought them like 5 weeks ago)

Beotko: i don't know what kind of feeder i have... but that spring is As hard as a mule quick, it doesn't matter i which direction i turn that screw, NOTHING HAPPENS!!!! at least i don't see anything changing....

i've noticed this:[media=2715][/media]

@cloackfiend: yes i've reader those posts too saying that if you need to go with play up to 230 is because your printer isn't working properly.... heheh the thing im printing is 20 cms by 12 cms, is a huge piece... i did several atomic pulls until now.. the material is coming our really white, without any contaminants, so lets see what happen overnight... @Fracfalco: A) im trying that right now, ill let the printer working over night and see what happens. b) about the file, how can i share it? C) you say that cura cannot coupe with surfaces???? so all this issues im having with the bottom top (surfaces) is an software issue?

@Cloackfiend: yes i can look trough the nozzle after the atomic pull, i did many many of them... is there other way to clean the nozzle without taking it apart or inserting things on it? after how many hours do we need to change the nozzle? im considering getting an olson block... im not sure because im the kind of guy that loves to use original parts...

hey Cloackfiend: yes ill love to triy printing this in 0.1 but it will take 45 hours! so thats why i choose the 0.2 layer thickness... what do you mean with äs the more layers, it does the cleaner it gets"?

@JohnFox :Thanks JohnFox, ill will try that too! i made the atomic clean several times, i turned the temperature up to 260 for a few minutes... so i think the nozzle is free, and no, theres no ticking sound coming from the extruder... what it makes me Angry and i don't know what is causing it... is the fact that the VERY first layer is perfect... really neat and smooth, but after that the next layers get worse and worse (but the shells are quite ok) is just the bottom and top layers that are not closed.... @Neotko: My PTFE coupler is like 5 weeks old... i already changed it...

Neotko: im in advanced mode, so i have: BASIC: Quality: Later height (mm) 0.2 Shell thickness (mm) 1.2 Enable retraction: checked Fill: Bottom / top thickness (mm) : 1.2 Fill density (%): 20 Speed and temperature : Print speed (mm/s): 30 ADVANCED: Machine: Nozzle size(mm): 0.4 Speed: (all are set to 0=30mm/s) besides the bottomlayer spped (20 mm/s)

new attempt, after doing several times the Atomic method... after levelling the build plate... using 0.2 layer thickness, 30 mm/2 1.2 top bottom thickness 215 degreees 25 infill don't know what else to say [media=2696][/media] everyone has a different theory about whats going on... Should i change the nozzle?

Well, im using 5 layers, and infill 20... But the problem appears really early in the prints, as i said, the first layer is perfect, then in the next 4 layers you can see that gradually the quality gets worse, that the layers are not closed, then comes the infill, and the rest is history. Im really considering getting an sledgehammer and finish this in an epic way... Im spending more time in searching and trying to fix stuff that printing... Thats nit the goal of the whole thing

Hello Forum ,the quality of my prints is getting worse and i cannot find an answer for it. the "roof" layers of my prints they look really awful. as an architect i need to deliver sometimes some "previews"of the plans as model, so i got this printer to save time, but, im getting tired of spending more time in looking whats wrong with the machine than being printing...[media=2688][/media] this is frustrating because the problems are so random.,, that nobody has an answer, my machine is in a good shape, got a new bowden tube, got a new ptfe coupler, the belts are thigh and all the moving parts are well oiled with sewing machine oil... the Very first layer is always perfect, but then the next ones, you can notice that gradually an under extrusion problem appears (i've printed almost all available tests online - for example that cylinder with volume marks - with to check if theres undersextrusion or not, and all the test prints are perfect. so now im very disappointed, and my opinion is that the design of the feeder mechanism hat some weaknesses. im not an mechanic Ingeneer, but for example, inside the mechanism, theres an spring that is doing nothing! no matter in which direction you turn the screw, the person on the filament will not be affected... i print it PLA from colorfabb, at 210 - 215 celsius degrees. and really slow, 30 to 35 mm/s and NO, im not testing stuff with my printer... this is so annoying...

Shhhhhh Still no luck with this issue, it seems the effect is worse using White PLA Colors
