beamo II - Flow Sensor Replacement

Tools

Step 1

Turn off the machine and remove the power cord.

Step 2

Remove the back metal cover.

Step 3

Remove the foam and detach the cables of the laser tube and the laser PSU.

Step 4

Remove the laser tube's holders.

Step 5

Disconnect the grounding cable of the laser tube.

Step 6

Place the rags underneath the laser tube on both sides.

Step 7

Remove the water hose clamp from the high-pressure side.
Make sure the water hose plug is ready so it can be inserted immediately after the hose is detached.

Step 8

Remove the water hose clamp from the low-pressure side.
Make sure the water hose plug is ready so it can be inserted immediately after the hose is detached.

Step 9

Prepare a bucket in advance to drain the water from the laser tube.
The laser tube can then be removed, and the water will be drained.

Step 10

Remove the laser tube seat on the left using a 3 mm Allen key (The one close to the water pump and the screen).

Step 11

Remove the front metal cover. (T8 torx screw * 10 pcs.)

Step 12

Unplug the cables on the laser PSU.

Step 13

Remove the four screws on the laser power supply.

Step 14

Remove the laser PSU and place it aside temporarily.
(The cable of the PSU is still connected to the laser tube at the moment.)

Step 15

Unplug the flow sensor cable from the mainboard and pull it out toward the flow sensor.
The flow sensor cable is wrapped and covered with white cloth.
Please refer to this diagram to identify the cable on the mainboard.

If there is a cable tie that ties the wires and cable, cut it off.

Step 16

Place the water container and rags underneath the flow sensor and water hoses.
Move the metal clips aside to unplug both water hoses from the flow sensor.
(Please note that water leaks when you unplug the hose. Ensure you do this inside the water container.)

Step 17

Remove the fittings with the water hose from the flow sensor.

A rubber spacer is inside the fitting. Please ensure that it does not go missing while removing the fittings.

Step 18

Install the fittings on the new flow sensor.

Step 19

Connect the water hose to the new flow sensor.

Place the flow sensor back into place.

Step 20

Plug the flow sensor cable into the mainboard.

Step 21

Place the laser PSU in its position.

Step 22

Fix the PSU with the four screws.

Step 23

Plug the cables into the laser PSU.

Step 24

Install the front metal cover. Ensure the Type-C cable's white dot is facing up as in the video.

Step 25

Reinstall the left laser tube seat.
(Make sure the cables and wires are all underneath the bottom openings of the seat.)

Step 26

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 27

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

Step 28

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

Step 29

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).
2. There are two short water hoses on both sides of the laser tube; they have to be horizontal.

Step 30

Place the foam back and connect the cables between the laser tube and the laser PSU.

Step 31

Add water to the system.
