    Selling my 2+

    in Buying or selling your UltiMaker

    Posted · Edited by Guest

    With pain in my heart I have decided to sell the 2+.

    Numerous reasons that I will not get into here, but nothing to do with the quality of this excellent printer!

    I have about 100 print hours on it.

    Original packaging.

    Comes with 16 rolls of ColorFabb PLA, and the original silver Ultimaker PLA.

    Some of the ColorFabb colors have not even been opened.

    Printer is located in Oregon, USA.

    Asking price for whole package is 2300 USD. Net to me Paypal fees, insurance and shipping on buyer.

    Let me know if any questions.

    Thanks,

    Why did it not stick to the bed?

    Well, as long as you are not printing ABS but PLA or e.g. XT there is no harm from nanoparticles or fumes in a non-ventilated room.

    btw: there are ventilation systems with heat recovery. They should exist even in the land of energy waste (called USA ;)).

     

    haha....am sure there are. As a european I can say there are good and bad things about the USofA!

    OK. Well, 15°C is not ideal, but it should work somehow. Usually you get angel hair when the adhesion to the last layer is lost. This happens if you suddenly print in thin air (skipping of the x or y motor) or if you had a temporary underextrusion. This could be caused by some additional resistance at the feeder (filament entangled?).

     

    So in winter, how do you get proper ventilation if the window is not open? By doing this temperature will drop....

    I have lots to learn, and honestly I dont know how to avoid the above situations you mention. I have not closed the window and am trying again...

    What's so good about Ultimaker?

    I have been asking myself the same questions....

    What printer? In all honesty I am not as hardcore as some others in this community that actually use the printer professionally or semi pro. I am a true rookie with a very steep learning curve.

    For me...printer had to provide good quality, i wanted to to be open source, and it had to look nice. I looked at a number of them, and in the end waited for CES to see what it would bring.

    As soon as I heard 3D systems was stopping with their consumer printers and U2+ was launched I placed the order and never looked back. So far I love it.

    Is it more expensive that some others...yes it is...but I see the value so far in community and the quality of the prints that I never imagined were possible!

    There is a reason why so many top companies and universities use Ultimaker...

    So I wanted to try an overnight print. Let it start its 14+ hour journey yesterday evening and upon waking up at 7am this morning this is what I found....

    Print size: 78/45/101mm...so a bigger robot!

    Robot was moving around on the heated bed....it didnt stick. As you can guess I didnt use the glue....

    Any idea why this happened?

    Could it be room temperature that caused it? We dont have heating overnight and I did leave one window a little open. Overnight outside temperature drops to 4-5C.

    Please advise.

    In mean time, I started another print.

    Thanks!

    Looking for tips on how to do this

    You can pause the printer and select change material. But my suggestion earlier is by actually printing 2 jobs. You just keep the first job in place, then select print and print the 2nd job over top.

     

    ahaaa...so in Cura I would need to design two things over each other and then delete the bottom part and only save the letters...then it will start print where it should, right?

    What you can do it make 2 stl"s one with the lettering the other the main body.

    The lettering just make it 1 layer thick and you print that on the glass. then you change the material and print over top of the lettering with your body stl.

     

    Thanks. I have lots to learn! No idea how to do this...and didnt know you can change the material in the middle of the job

    Ultimaker 2+ Extended first impressions are awesome

    Thank you....

    So what is gcode?

    Do I need to run the test print a few times or will it adjust temperatures within one print?

     

    https://www.youmagine.com/designs/quick-temperature-fillament-test

    There is an STL but also gcodes to download directly.

     

    Newbie question....what is the difference from gcode and stl?

     

    STL is your 3D object (it's the extension of the file also) and Gcode is the output from your slicer. (Cura, S3D, ...)

    Gcode contains the information for your printer, what temperature to use, speed, coordinates for you axes, ... (you can open a .gcode file with a texteditor to take a closer look at the file)

    Other obje

     

    thanks! so far I dont think I ever downloaded the gcode but only stl to the sd card....but I also dont think Cura created a gcode for me so far..
