7.19.1 Replacing the IF PCB
(1) Turn off the power to the CNC, then turn off the main circuit
breaker and power supply for the laser oscillator.
(2) Disconnect all cables from the IF PCB.
(3) Remove the screws or edge supports, then remove the interface
PCB.
(4) Mount a new PCB by reversing steps (2) and (3). Connect the
cables, noting the alignment marks. Ensure that no terminals are
loose. Check that the connectors are connected firmly.
(5) Set the jumper pins to the same status as present before the
replacement.
(6) After the replacement, no adjustment is needed.
7.19.2 Replacing the Stabilized Power Supply
(1) Turn off the power to the CNC, then turn off the main circuit
breaker and power supply for the laser oscillator.
(2) Remove the IF PCB.
(3) Disconnect all cables from the stabilized power supply.
(4) Remove the four edge supports, then remove the stabilized
power supply.
(5) Mount a new PCB by reversing steps (2) and (4). Connect the
cables, noting the alignment marks. Ensure that no terminals are
loose.
(6) After the replacement, no adjustment is needed.
7.19.3 Replacing the Input Control PCB
(1) Turn off the power to the CNC, then turn off the main circuit
breaker and power supply for the laser oscillator.
(2) Remove the IF PCB.
(3) Disconnect all cables from the input control PCB.
(4) Remove the four edge supports, then remove the input control
PCB.
(5) Mount a new PCB by reversing steps (2) and (4). Connect the
cables, noting the alignment marks. Check that the connectors
are connected firmly.
(6) After the replacement, no adjustment is needed.
