Safety Instructions
Gantry
Z Stage
Door Locks
Interlock switches are used to communicate the status of the oven door and the top cover to
the printer. For safety reasons, the oven door and top cover must be closed before the X, Y,
and Z motors will operate.
Warning: Moving Parts.
Never wear a tie, loose clothing or dangling jewelry when working around moving
components of the printer.
Beneath the top cover of the printer is the gantry. This area houses the mechanical
drive components of the X and Y axes. Use extreme caution whenever accessing
this area of the printer.
The printer's servo motors are disabled when the oven door and/or top cover are
open. The XY pinch hazard between the timing belts and pulleys is minimized by
locking the oven door and top cover while building and disabling the motors when the
oven door and top cover are open. The oven door and top cover automatically lock
when the printer is building and cannot be opened while the printer is building. You
cannot start a build if the oven door or top cover are open.
Warning: Moving Parts.
Never wear a tie, loose clothing or dangling jewelry when working around moving
components of the printer.
The drive belt, pulleys and Z stage servo motor can cause severe injury. The Z stage
crushing hazard is minimized by locking the oven door during Z stage moves and
disabling the Z motor when the oven door is open.
