    • Slipping pulleys or gears or belts can cause the print to slightly shift and start leaning. Tighten pulleys/gears/belts to stop this happening. ( as you explain , you do it )
    • Friction along the axis might cause it to lose steps. Just a few steps here and there, enough to make it lean. Clean and lubricate the axis so there’s no friction.
    • A misaligned printer frame or bed will result in a leaning print as well, check everything is as straight as possible.
    • Check Current in your stepper drivers and tune it acording motor datasheet.

      for the rest look on facebook , reedit, amino for other group about Anet because you are on ultimaker forums here , there is an example forum you can get more help https://www.3dprintingforum.org/anet 😉
  1. Hi there, is been a long time 🙂

    im back again with a new ridle with a UM3.

    so wath' is the problem ? yes, let me in 

    for explain simple, there is "slipping" on Y belt in the machine while X travels.


    for be more simple, there is the video in "slo mo"


    i tried re align all the pulleys and re tigthen everything but nothing do it.


    BTW, it hapens one everytime machine starts rigth after a homing but after it no more hapens during stress test or other movement of the XY square.

    can it be a electronical problem ?

  2. neotko : is ordered, but i can only use the old one for now and think use it to the end or when they redo bad prints, i think i already receved when this will pass :) .

    gr5 : yes, main problem are fixed :)

    ah, i not tell, i put pc thermal paste on ceramic nossle heater when remounted it . now plastic extrude at perfect temp :)

  3. hi again all.

    like promise, i keep u tuned and we can close the thread ! Lo/

    so, for X/Y it was the gear on one nema 17 they was semi uncrewed so "voila"

    and for the nozzle , they was cloged, i unmounted all metalic parts

    put all on a 50/50 WD40 + ACETON glass for 2 days

    used a gaz torch for heat it all after dry them

    removed burned things

    uncloged nozzle, and drilled very ligth the inside before reput it on a new mixture of wd/aceton for a day

    be carefull with them because I have been forced to tap the aluminum heat block before rescrew all ( aceton i presume )

    so, not changed peek and ptfe coupler but seems work fine again :)

    thx !

  4. found LM6LUU are rusted on central X/Y part i will buy sommes tommorow and try.

    for quality print nozzle i think buy this kit for be sure get all necesary parts https://shop.ultimaker.com/product/2/HotEndUpgrade

    i dont want to be sad, but for a 1200$ printer, is a bit weird to replace so important parts , its cost 2 roll of 3Mm PLA lol. ( i said this , but i think is maybe not better with china rep-rap's xD )

    so i stay you tuned , have fun! :)

  5. okay, where i can buy a kit and for how much ?

    the ptfe coupler are the original we get when buy the UMO+ but dont have caliper, so i made a measure picture with wath i have


    and how about this bad x / y ? i read about bad sd card stuff somewhere they corrupt gcode but dont have bad pin in sd slot of controll panel. i want try to print something via usb but not see any option on cura. i got a aduino 2xxx on windows controll panel and dont know how to do.

    ( i have a netbook with ubuntu studio if necesary )

  6. peggyb : dont got fan under machine

    Dim3nsioneer : i can play through the fire and flames solo on belt :p

    nallath : a bit too hot maybe , is old esun filament ( dont got other for the moment ) i need to found the rigth temp setting for this one.

    etienne-martin :

    - screenshoots of cura config comming soon.

    - look wath i said to dim3nsioneer & nallath

    - expect usual working noises nope , and there are rigth screwed

    neotko : did you have a instructional video or can you tell me it on french ? im not sure to understand all , so , i teardow maximum accesible nozzle parts as i can and send you wath i've do .

  7. i have tryed to print with other item, and seems is from printer but in a diferent way now.

    like something stop axis at certains ways. i have already put wd 40 on these last day and watever i place item on other place of the plate i get same stuff . im loosing my head :v

    im a bit in the cloud because im just waked up today and english not my native language. so sorry if im not engouth precise.


    i have do wath you telled me, adedmore retraction, and improved a bit but dont know how to use sketchup for repair the model if is the bad guy .

    new problem and i presume it was here before just not noticed to now : sommes filling layers goes out of the printable piece and also inside look closely, i presme this is partialy why i have caped semi-hole on the side.
