Project Dashboard Accessories and Upgrades Graphical LCD Controller Installation LulzBot KITTAZ Workflow

1 Before Beginning

The Graphical LCD Controller (GLCD) is an optional add-on for the KITTAZ 3D printer. This add-on allows for printing without being connected to a computer using its integrated SD card reader. You can also monitor your prints progress and view live information about temperatures, settings and modify some settings on the fly, without having to reflash the firmware.

4 Remove Frame Corner

This next step is best performed with the Y axis assembly removed and with the main frame of the printer laying down.

  • Remove the triangular frame connector from the top left hand corner of the frame.

5 Install Graphical LCD Case

  • Keep the two M5 tee-nuts in place on the printer frame and use the existing screws to secure the Graphical LCD controller enclosure onto the printer frame.

  • Once secured, install the Y axis assembly back into the printer frame.

6 Install Graphical LCD Case Cover

  • Use the 4 M3 12mm screws to secure the front panel onto the Graphical LCD controller.

7 Connect the GLCD harness

To identify the connectors on the wiring harness, follow the large black connector.

  • The connector EXP 1 has the majority of it's wiring going to the larger black connector.

  • The connector EXP2 has wiring leading to both the large and small connector.

  • Connect EXP 1 to the left hand connector socket (when looking at the rear of the GLCD enclosure).

  • Connect EXP 2 to the right hand connector socket.

8 Plug in Cable

  • Plug in the large connector to the connector on the RAMBo electronics labelled EXT-2.

  • The red wire on the large black connector should be oriented so that it's close to the silver USB port.

  • The smaller connector is plugged into the connection labeled SP1. The connector is marked with a triangle to designate pin 1. SP1 is labeled with a small 1 to indicate orientation.

  • On each black connector match the black triangle to the Pin one locations noted on the board and in the image below.
