    re calibrated the Z axes, used your setup on speed
    this is the 15mm cube
    the bottom looks perfect (Pic 4)
    but the sides are wobbly

    any advice ?

    I would check both the belts make sure they are tight enough they twang a little bit if you pluck it like a guitar


    This sides of teh cube appear to be flat (other than the wobble) meaning they are not bowed out or concave so that indicated your flow is about right if they bowed out it is to much flow and concave means too little flow this is regular and repeating. I have an idea is the wobble on all sides if it is it could be the set screw is not really tight against the spindle on the motor and it could be moving just a bit back and forth on each direction change which would give the wobble on both sides. Left and Right for one axis and front and back for the other.

    A few things too think about at least

    Has anyone come up with a "belt tightener" of sorts yet? I've found it to be VERY difficult to get the X axis tight as I'd like it, and it's certainly not "tight enough to pluck like a guitar string"! I was thinking maybe some sort of clip with a tightener bolt that allowed you to take up the slack maybe 10-15mm. Wrapping it around and then trying to zip tie it got some some more tighteness, but certainly not what I would consider enough... and I have seen an issue which I think could be attributed to the belt being too loose (or maybe the stepper missing a step) but I'm prone to blame belt tightness (or lack there of) first.

    I have a simple process but it works but I need to find out some details on your set up as I recently found there are subtle differences

    Try me on skype Jeff Janes or jj.tessereact send acontact request with your username on this forum so I know who you are on skype in case it is different LOL

    Oh YEAH Baby!!!! I've tightened my X axis belt good now! :D :D :D

    The trick... getting it as tight as I could by hand, throwing two zip ties on the belt to hold it in place, and then tossing this on the belt: http://www.thingiverse.com/thing:81991

    Let's just see this belt TRY and slip now!!! ;)

    Still need to do the Y axis... but I'm MIGHTY happy with how well that worked out! :D

    @Matt Does that not collide with the pulleys/bearing?

    I used it only on the X axis. There's enough room to slip it if you position the motor in the middle of the axis and clip it onto the top part of the belt loop. There's no room on the Y axis for it so tightened it traditionally.

    I just found out that my filastruder is putting out 1.6mm filament (thanks Jeff for making me look at this)
    thats why my hobbed bolt isn't grabbing it correctly and when it moves to the sides it goes way out of the threaded parts

    also, my heat bed started to turn off at 68°C. i guess i need to do the relay switch upgrade.

    i'm waiting for my Robo3D filament to arrive. gonna be using PLA so the heat bed will be on vacation for a while

    Just received my Filament ...yay !

    although I'm disappointed in the "Robots" making the packages, they are unaware that i have replacement parts that i was told they will be sent out

    oh well ...

    why does this happen ?
    first layer was great, but as soon as it went up it started messing up

    You could have partial block the first layer usually is set to print much slower so at some level a partially blocked extruder could be over come but when it speeds up the extruder begins to show signs of the clogging

    problem is i don't have a PTFE tube
    I tried finding it around here but no luck
    if i ask Robo team to send me one its gonna cost me around $18 in shipping alone
    can i use it without the tube ?

    no it is a heat resistant liner that allows the different materials to move without clogging without the different elements could get warm and possible melt to the inside of the chamber not sure where "here" is and forgive me if you told me lot of people have been talking with me but we can order it online locally also could you do the same. Some one yesterday was talking about getting a meter and he only needed about 4 inches total but it was the only way they sold it
