Update - all fixed - rusted motor bearing was the problem.

Have done this - all sliding blocks move well on their own, I think the problem may be the Y servo motor? Any advice? Tia

Thanks so much, I'll try this!

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
