700 hours and still going

700 hours = 20 hours a day x 35 days over the course of about 8weeks (slight breaks in between)

i teach 3d printing to kids and this machine has held up no problem with kids doing what kids do.

only few issues i've had so
- y axis belt was very very lose (easy fix)
-z coupler hole center was misaligned (got replacemnt from 3d)
-about to wear the y axis metal rails out, black plastic dust is coming out the back of my rails gliders(got replacement from robo3d ordered)
-limit switch installed backwards(will fix once i get some downtime)
i went ahead and ordered the rail shaft upgrades.

robo3d pla version 300microns not a single problem with over 250 prints.
