    So, after much struggle i was finaly at a point where prints where ok, but now im at a new problem.
    Wile fidling with the settings i thought id try repetier aswell, seeing as alot of ppl seem to prefer it.
    After installing repetier i can no longer use matter control, i just get a slice error every time.
    And my experience with repetier has been of rather poor quality. It prints, but ohh so much slower with the same settings. And it also fails prints that mc would print fine.

    Any suggestions? I tryed uninstalling repetier again and remove all old remnants of slic3r that came with it, reinstalled mc but still no go.

    So now im stuck with repetier, and im struggling again to even get a descent print.

    Not realy helpfull when i try to figure out what is wrong.
    Added a scrn of the mc error. Its not saying much but if anyone has encountered it i would be great full.
    Mc and repetier has theyr own version of slic3r in theyr own folders, even on sepperate harddrives so i dont realy see the problem.

    I don't use matter control. It would be best if you created a new thread for this issue as anyone trying to find it wouldn't know that a thread about globs would need help with mattercontrol. I would also ask on matterhackers.com forums, they probably have more experience with matter control http://www.matterhackers.com/community/forum

    Click on the MC left icon to load the object into the viewport.

    Take a screenshot and post what it looks like on the bed.

    Maybe it's
    Hanging off the bed or not on the bed, as in hanging in the air.


    Send us the screenshot and we'll be able to get a better
    Guess at the problem.

    Also check your setting for the Robo bed size I MC.

    Which problem? The delamination, the rough edges, the top unfinished?

    Can't tell from the picture :)

    Delamination is a heat transfer when the layers is being placed. Either the layer is slightly high or the temperature is slightly low. In either case the layers will not fuse correctly.

    P.S. is this is ABS then situation normal, but the temperature around the print is too cool.
    (I assumed this was PLA.) about the only things you can do then is run the extruder a bit hotter and make sure no fan or air circulation is happening around the print.

    Hehe, point taken.

    The rough edges and the delamination. Top unfinnised would be my mistake.
    This is pla. Ive checked every belt, pulley and bolt/nutt on the printer.
    I saw some hairy parts on my prints wich led me to belive it was to hot?
    The auto cooling feature is turned on, think i saw people mention that i should have it on with pla?

    Layer hight is 0.18 or 0.1834 to be exact.
    I am now printing at 200c seems high for pla, no?

    Only thing I can suggest is that the initial Z height is too high. That would then cause the layers to increasingly be off. The rough edges could be a loose belt, but easiest way to sort them is to slow down the speed a bit and the acceleration a LOT (cut accel to < 100, certainly < 1000--the default is 9000). Even is the belt is just a bit loose, cutting the acceleration will sort it.

    Do you happen to have a link to what the accel realy does?
    I did lower it to 3000 per some other instructions somewhere on this forum.
    is there any negative effect of lowering to sub 100?
    And why is it not like this from factory :p ?

    Thanks for all the replyes.

    Acceleration is how fast it changes speeds. Think of it as 'jerk'. Having it slower will somewhat slow down the overall speed of a print, but not enormously.

    Why it is is like that from the factory? It is a software setting, most software defaults to max. I am not sure why the custom version of matter control (or whatever they ship with the printer these days--I do not use them) is set that way. It is not a huge performance hit to drop it. You could adjust the belts more, but there is a fine line between tight enough and too tight; so (to me) adjusting the accel is a quicker, simpler fix. If that does not get it to where you want it then you need to tighten that belt a wee bit more.

    I see, Thank you for the clarification.

    What do you suggest for acceleration steps then?
    I guess its x,y extrude and retract that are the importent ones?
    Just noticed that my printer doesn't save the settings.
    I get it to write to eeprom, but somehow after i shut it down last night its back to the defaults again this morning.
    Or am i totaly getting it wrong and these settings should be altered somewhere else?

    Alot of questions, but I am werry thankfull for the answers i get.

    They are set in the software (like Repetier). I use Simplify3D so I doubt yours is the same. Attached is a screenshot from Slic3r.

    Whatever you use, look for these settings in there (somewhere near speed settings)

    Aha i see. i just thouth these settings where changed in firmware. Because that was what the discussion i got this from was about.
    [​IMG]
    This is where i tried to change the settings. Found this in repetier.
    But i will try to change them in slicer instead.
    So the 500mm/s values are nice places to start?

    You can go as low as you want or as high as 9000 (that was the default).
    For me, back when using Repetier/Slic3r those were good numbers.
    With the new software everything works fine at max acceleration and speed.
