I’ve fitted the new laser chiller this evening, and the laser should now be
cutting consistently again.
The chiller is to the left of the laser cutter. MAKE SURE IT IS TURNED ON
BEFORE USE. It can be turned off when the temperature on the front is less
than 25, or after 2 minutes (whichever is the later).
For reference, it was cutting well at power 100 speed 5.
