Y axle lowered and touching belt on S5 printer.


Recommended Posts

Posted · Y axle lowered and touching belt on S5 printer.



I have 3 brand new Ultimaker S5 printers, and one of them seems to have a problem.


Specifically, the Y axle, at the point where it is hooked into the black plastic cover (the one between the belts) seems to be lowered, and would sometimes touch the belt while printing.


I have attached a video and some close up photos for you guys to see. I am not sure if I should just re-tension that specific belt, or if I need to also re-attach the axle properly, somehow, before doing that.


Any help/input is appreciated.

    Update: The axle was actually not locked into the black plastic box, so we snapped it back in and everything appears to be ok now.

    However, we didnt snap it in perfectly centered, so now the entire axis is pushing towards the front, making the black plastic box in the front sit at an angle, and not perfectly vertical. Is it ok to open said black plastic box (as I see it has 2 small hinges), un-lock the axle, and then snap it back in perfectly centered? Or should I just leave it as it is.

    Hi Cosmin,


    @fbrc8-erin has posted a good tutorial video about reseating axles and sliding blocks on youtube:

     It's for the UM3, but the procedure is the same, as the sliding blocks are identical at UM3 and S5.


    Taking apart the sliding block is not necessary.


    This video shows how the sliding block is assembled (just for your interest):
