A missing fuse can often be identified by the laser failing to fire, or the z-axis failing to move up or down. The fuse is meant to be field replaceable but appears to pop out when the crated laser is given a significant jolt (like with a forklift or pallet jack). The fix is very simple by removing the chiller and placing the fuse back in its correct spot.
Here’s the process:
- Turn off the power to the laser, and wait 10 seconds
- Unplug the power to the laser from the wall
- Clear a path to the right side of the laser
- Using a Phillips head screwdriver, remove the two screws holding the chiller in place (One is to the left of the spigot, the other is to the right of the fan intake)
- Carefully remove the chiller from the side of the laser (Be sure to “carry” the weight of the chiller if it’s full of water, to avoid damage to the cable or tubing)
- Observe the 3 fuses inline that are behind where the chiller sits (photo attached).
- Reseat any loose fuses
- Replace chiller and power on laser
You’ll notice in the photo below that one of the three fuses is not seated.
Press the fuse firmly back into place in the same orientation as the other fuses, and reassemble the machine before testing whether the problem remains.
