Gantry Maintenance
Re-Equalize and Synchronize the Gantry
It is possible for the gantry to become twisted such that is not perpendicular to the tracks. This is usually caused by an obstruction on one track that stalls that side of the gantry and mis-aligns the system, or a loose belt on one track.
If a belt is loose, follow the maintenance tip above for tightening the belts.
If the belts are tight and the gantry is twisted, re-equalize and synchronize the gantry using instructions on the gantry page.
Preventative > Reactive
Even if your belts are tight and the gantry moves across the tracks fine, the gantry could still be twisted and causing unnecessary stress and wear to the components. It is recommended to re-equalize and synchronize the gantry twice a year to ensure that it stays perpendicular to the tracks, even if it is not noticeably twisted.
