    Hi guys,

    I built my Acro 1.5m variant for an experiment. It working pretty well and it's fairly smooth.
    But I see that after many movement cycles, the stage doesn't come back to its original position. I have checked if the timing pulley is jumping across the teeth on the timing belt but that's not the case. I put it in hold condition and the stage doesn't move easily. So I think that sometimes, the stepper is slipping while accelerating.

    I currently use Longrunner brand NEMA 17 motors, driver: https://www.amazon.com/Longruner-Arduino-Professional-Mechanical-LKB02/dp/B072N4FMRN

    Do I need to use motors with higher holding torque? Would it suffice to use a higher current capacity driver?

    Any help in this regard would be appreciated.

    Thanks,
    Subhash
