SAFETY PRECAUTIONS
The following components and areas of the printer are potential safety hazards. Take adequate precautions
when using and maintaining the printer.
OVEN
Warning: Always wear safety gloves and long sleeves when working inside the
oven. Components are hot.
Note: Opening the oven door shuts the oven heaters off.
GANTRY
Warning: 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.
Note: 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.
Z STAGE
Warning: 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.
DOOR LOCKS
Sensors 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.
