Disabling The Safety Interlocks (Door Sensor Checking Board)

Preface: This article covers how to bypass the safety interlocks, the location of the door control board and safety warnings that should be followed if the user bypasses the interlocks.

It is 100% your responsibility to operate the machine in a safe manner. Thunder Laser USA assumes no responsibility for any damage, harm, injury etc. that may result from the bypassing of the machine safety. You should wear the proper PPE like safety glasses, inform anyone in the immediate area and take all the proper precautions to protect yourself and others from injury. The exhaust will not be as effective either, take precautions to extract the fumes that are output from the laser. Bypassing the interlocks will make the machine a Class IV type, with direct exposure to a Class IV source possible.
