Hi all,

Our UM2 is stuck/making a grinding noise on Y-travel, also can't move it manually. All good on X. None of the belts are visually slipping when the noise happens, and all are tensioned well. Any one had/fixed the same issue, or got any tips or advice? 

Thanks

    I had this exact problem (except it was X axis) on a UM2 (not my printer but I fixed it for them).  It was hard to tell but they had sprayed some kind of glue or something and it was over many areas inside the build area.  Anyway diagnosis is the same regardless.

     

    Start loosening the 8 pulleys on the long belts - well really the 4 on the long belts for the bad axis.  With power off move various things.  For me it was one of the 4 sliding blocks wouldn't budge (the one opposite was fine but that was not obvious until I removed the head and loosened all the pulleys).

     

    The 2 rods that go through the print head - pop each end out one at a time from the 4 sliding blocks.  Then twist the head and lift it out of the printer and put aside.

     

    Once you know the problem area I had to take apart one sliding block and remove the whole rod from the printer.  I brought the rod and copper sleeve bearing to some heavy duty tools area and used hammers and vices and things to get the copper part to slide (first clean the rod well of anything on the surface - maybe some fine polishing with 1000 grit or so).  Eventually I got the copper part off and was able to clean the two parts until they slid nicely and then reassembled everything.

    Thanks so much, I'll try this!
