Sometimes during transit there is a fuse that is coming loose and will prevent the laser from turning on, or the z-axis from moving up and/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
- 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” weight of the chiller if it’s full of water so as not to damage cabling)
- 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.
