OK thanks for the info.

Thank you, the press seems to me that it was to 203 ° C with the next try to print to 195 ° C

Thank you. I then try to increase the speed of retraction of 1 or 2 mm / s

Hi guys. I have never had these problems. I think it is as if the extruder is stopped in an instant more or rests on the printed side before moving and let these ugly marks on the print. attaching photos to better understand my problem.

I understand, the z axis is spotless, I clean before making the various tests, but I can tell you that before I made the change of the filament, when normally I printed with wires from 2.85mm happening to me this problem of over-extrusion only when I used a height of 0.2mm to 0.1mm but if I printed out a perfect printing!

Hi gr5 , I have done these three tests. Before printing layer with height of 0.15 and 0.2 then to finish 0.1 naturally adapting the speed and leaving the flow always equal to 100%. In all cases I had over-extrusion, and in the case of printing to 0.15 when in fact the upper part there was even a little is under-extrusion.

Hello guys! is for more than one week I am trying to solve problems of under-extrusion or over-extrusion. In this photo I have an example of three identical prints by changing the layer height and adjusting the speed. I started with 0.2 and then continue with 0:15 and finally 0.1 In these cases, I have always had over-extrusion of the cubes in the walls and only if what I had 0.15 in the even greater under-extrusion. I would understand if it's just a problem of feeder and what evidence do I need to do to try to solve?

OK I'll do the tests

Hello guys! Can any of you explain to me what solution is best? What use you and how you are? Lacquer on hot dish is what I use, but I've seen that too many people who do not use it anymore! Second Buildtak solution (I do not know how it works) Third solution (blue plate) Fourth solution (brown plate)

Today I tried to do other tests. Maintaining the same print file but changing only the esteps values.

Hello guys! I had the need to change the diameter of the filament in CARE and after a tip that was given to me, I went to machine setting and I modified GCode Flavor I initially put Reprap Volumetric but printing is coming very badly, I had excess material in other cases under-extrusion. I then saw that the same thing could be done by amending RepRap (Marlin / Spinter) and things become similar to when you leave CARE with the default settings. Does anyone know tell me why this happens?

Ok you're right no post double!

I understand you, and I'm grateful and I thank you for help and your availability. But is it really a big mess for me to solve this problem and stop the work that I require, so even if exaggerating, but I'm trying to get out as fast as possible. But they disagree on the limitation of the community! Because in Italian language there are no experts who can help me and then I do not think it is right to limit itself to a comparison between only members of the same nation otherwise you would have had to do the same with Spanish users.

Before moving the material I have marked with a pen. Then I told him to move up to 100mm and has moved 100 millimeters then it would seem that the material moves to the correct size.

Today installed the firmware of tinkergnome on my Ultimaker2 specifically the version 16.08.2 on my CURA version 15.04.6 Can anyone explain me how to fix in the best way the esteps and all related to the feeder parameters to improve print quality as it was before when I used the filaments of 2.85mm Now I have always under-extrusion and a bad print quality. I have to solve retention problems and even problems with printouts particularly demanding as those of the bridges or unevenness at 45 degrees or more. I include photos to better understand! It would seem that ventilation is no longer as effective as before! The levels of the print layers are a little more obvious than before, also it seems to be one that slips over the other. and no longer as first one in line with the underlying.

Thanks Perfect I solved

I have to learn how to fix the setting of esteps and all other parameters in order to make quality prints. I need to understand how to improve the efficiency of the machine in order to have quality.

I had to set these values to avoid retraction of no good prints. From what I understand, however, how high the esteps error feeder, these problems have come out after the filament change, since I converted my UM2 to the filaments from 1,75mm.

I can not understand what you want me to ask.

Hello guys! Is there a way to change the value of the filament diameter in CURA 15.04.6? Because now that I switched to the filaments from 1,75mm not properly calculate me the meters of filament needed to make printing. I have tried in various settings but can not find the option to change this parameter.

Thanks for the answer. You have not wasted a single minute. I have a UM2 and I mounted the extruder from 1,75mm of 3Dsolex. Ok but can you be more precise in how to set esteps and how to understand what you have to move the filament?

Hi ultiarjan, Can you explain once I upgraded the firmware you're talking about, how can I then go to appropriately modify all the parameters of esteps and other parameters of the feeder so as not to have more problems under-extrusion?

Hi, Can you tell me the parameters that you used to recoil when printing the CtrlV M4 tests and also for other prints. And then as you have changed the values of esteps? If you have mounted a MK8 for the feeder? I too have problems of under-extrusion since I switched to the filaments from 1,75mm.
