MAINTENANCE
Regular maintenance is important for accurate worry free printing. Perform these simple steps to optimize your printing experience.
CHECK BELT TENSION
Every few weeks it is important to make sure the belts are the correct tension, as they may stretch out during use. Follow the
instructions in the Belt Tension section if you suspect a belt need to be tighten. The belts should be checked every few weeks for
casual use and every week if the printer is used daily. Checking the belt tension regularly will help prevent print failures and/or
damage to the printer.
CHECK PRINTER BED LEVEL
Verify the bed is level every 5-6 prints. In addition, the bed should be leveled after replacing the Scotch Blue Painter’s Tape on the
bed or if during removal of a part you feel the bed may have shifted. Check the bed level by running the bed leveling program (See
Bed Leveling section).
