Step 19

Rewrap the cable wrapper.

Step 20

Plug the 28-Pin & camera cable to the X-axis board.

Step 21

*Make sure you use the same screws as in the video. The screws for the metal front/back covers differ from those for the X-axis board and the 1st mirror holder.

Step 22

Reinstall the laser tube bottom seat.
(Make sure the cables go underneath the seat openings.)

Make sure the grounding wire is connected to the terminal.

Step 23-1 - Install the laser tube

Place the laser tube on the machine and connect the grounding cable to the terminal.
(The grounding cable has to be on the same side as the other one.)

Step 23-2

Step 23-3

From the low-pressure side, remove the hose plug and connect the water hose to the laser tube.

Step 23-4

Fix the laser tube in place. Please note these two points:

1. The distance between the laser tube's nozzle and the first mirror seat will be around 1.5cm (one finger).

Step 25-2

• There is a voltage switch for 115V or 230V. Please switch to the correct voltage that suits your environment. (For example, the US is using 110V, so 115V will be switched to. The UK is using 230V, so 230V will be switched to.)

• Place the laser PSU in its position.

Step 25-3

Fix the PSU with the four screws.

Step 25-4

Plug the cables into the laser PSU.
