CNC Laser Cutting System

Laser cuts on one side of machine and will not maintain cut.

1. Make sure all mirrors are clean.
   
2. Make sure all mirrors are properly aligned and light spots are taken at each mirror.
   
3. Check that laser tube is firmly secured in locking cradle.

Laser will cut through a certain thickness of material, using the proper power and speed settings. After a short period of time, the laser no longer cuts through the material using the same settings.

1. Check the laser’s light path and make any adjustments to mirrors if alignment is off. This process can be found in the Techno CNC Laser User Manual.
   
2. If mirrors have been aligned and the issue continues, go through the proper procedure for removing the laser tube. Once the tube is removed, check that the tube’s brackets mounted on the machine are tight and secure. Loose brackets can cause the tube to shift during the cutting process, skewing the light path. Once brackets have been tightened and secured, go through the proper laser tube installation process and realign the light path.
   

Machine randomly stops in the middle of cutting and requires reset. It is also observed black burning or arcing is burning laser safety enclosure.

Possible solutions:

1. Check to make sure proper ground is connected to machine. It is recommended a dedicated 6 ft. ground rod is installed

2. Check to make sure laser tube rubber boot is properly installed over the end of the laser tube, and fuller covers screw terminal. (See picture below.)

The rear breaker randomly trips and requires constant attention.

Unplug the water chiller and pump from the rear power source of the machine, and plug directly into wall outlet. If this does not rectify the problem, then the main control board needs to be replaced.
