    Thanks for the advice, I will find time to read through the article, It's a big help to me,

    I was wondering if there is a graph that explains settings of Cura, so one can understand it visually.

    Thanks for the idea, I will try to set the temp to 200 and give it a shoot.

     

    overhangs test

    in Improve your 3D prints

    Hi there,

    I was testing overhangs on my Ultimaker 2 with this model :

    https://www.youmagine.com/designs/egg-cups#!design-information

    and here are the results:

    IMG 5587

    IMG 5588

    IMG 5591

    it created lots of strings and bumps on the upper part of the print, my print settings are:

    layer height: 0.1mm

    Head temp: 210C

    build plate temp: 65C

    speed : 40mm

    retract length: 4.5mm

    retract speed: 25mm

    is my print head temperature to high? or maybe I need to raise the print speed?

    any advice would be appreciated.

    Thanks for the advice.

    I've also found that they has a product descriptions as below:

    We in average spend 2 weeks to test and characterize each new PLA or ABS material, diameter and color combination in many different semi-automated print tests. Above and beyond the manufacturing quality control, we re-run these printing tests on different 3D printers like Makerbot Replicators (PLA 1.75), an Ultimaker 1 (PLA and ABS 3mm), an UP Plus (ABS 1.75) and 2 RepRap variants. They are run on a quarterly basis to ensure we always ship a product that provides reliable and repeatable print results when using ExcelFil high quality ABS and PLA plastic filaments.

    It seems like they had tried the filaments on Ultimaker original.

    Do I buy that? It looks like a bet :sad:

     

    strings and spots on the print

    in Improve your 3D prints

    I printed two models that have been placed one after another at the same time, here is the result:

    marvin 2

    marvin 1

    marvin 3

    Some strings and spots came out between them, It seemed like the nozzle was oozing while moving between prints, any advice on how to improve that ?

    here is my settings:

    marvinPrintSettings 1

    marvinPrintSettings 2

    marvinPrintSettings 3

    The build plate temperature is 60, nozzle temperature is 210 ,

    Any advice would be greatly appreciated.

    Sorry for my poor english :-/

    gr5 and IRobertl, thank you for the advice.

    I have found the wire on the image below is the problem, I have marked the problem wire:

    fanWires 2

    when I was going to TUNE menu and set fan speed to 100%,

    the fan didn't run, but when I push the wire toward the connector , two side fans came on.

    so the next step I need to do is disconnect the wire and reconnect it and see how it works.

    wish me luck!

    I went to TUNE menu and set the fan speed to 100% , the fans ran and reacted

    to the fan speed command in the menu correctly, but when printing was starting the fans became on and off randomly, please see the video below:

    It seems like the movement of the print head randomly stopped the fans, I guess.

    Also , before I start to check the wires I wanted to be sure the red line in the picture below is the mesh sheathing stuff, right?

    Thanks for all the great tips!

    I've made my third print with Ultimaker 2 this morning, I scale the owl model down a bit from the original size,

    I've set the minimum layer time to 7 seconds in Cura and build plate temperature to 60C ,

    here are the rest of the Cura settings:

    setting 1

    setting 2

     

    Here are two clips that shows the printing process:

    Here is the result:

    thirdPrint 1

    thirdPrint 2

     

    The middle part of the owl was still got some distortions , I've found the back fan on the print head was running over the printing, but the two fans on the side were coming up randomly, as you can see at 3:50 in the first clip.

    and in the second clip you can see the side fans were not moving at all, is it normal?
