    Cube 3 printer problems

    Hi everyone - first time poster as so far..its worked.

    But after spending hours fixing cartridges it now just prints a thin strip over and over (see pics)

    after running a self level, ive just realised the print head aint moving side to side - im guessing thats my problem

    any ideas on what is wrong and how to fix it please?

    thank you

    Check to see if the belt is connected to the print head. There is a common problem where one or both of the set screws on the head have cracked the plastic housing. My friend had this issue and it completely broke through the housing. You may be able to repair it with epoxy. In his case, he had just bought the printer so he returned it to the store.

    yep - found the culprit - a little plastic bit with grooves to engage the belt. it had cracked and come off

    tried to take it apart - got as far as the back plastic cover - its like a rubies cube!

    won't know if I can attach it back until I get to the back of the print head proper

    cheers

    The left fan was not working, were I was experiencing extruder over-heating...


    I ordered this one:

    Specs almost match except. Hope it works, as buying one with matching specs would cost ~ $17+

    The one in the Cube is # MF50151VX-B000-G99 and Only Alibaba seems to have them. Other sources have MF50151VX-B00C-G99

    You will probably find the cheaper fan under-powered. That 2.04W is a hard target to hit with generic fans. My preplacement added an extra wire for sensor feedback that can be ignored for full power. Probably a hall sensor. But yes, these are not cheap!
