I seen this error on DJ500, Z3100, Z3200 & caused by :

worn out belt

belt's tension  ( twisted wrong direction also )

encorder strip on dj500/800   (   on right side where it entered  through bracket not properly )
my last repair on Z3100 44"    scan axis motor   (   right side above service station )

You have to open the covers & carefully look at the carriage box movements & see where exactly it stop, sound

& error come up.

for reference only & I do not have your model.
