Orange is back in action. Please note the following.
To prevent damage to the tube, there is now a flow sensor in the cooling
system. If no flow is detected, the laser will still move but not fire.
The cooling system is having an occasional issue where it doesn’t come on
properly when you have turned the laser cutter on. If this happens, unplug
the grey cable from the back of the laser cutter, wait 20 seconds, and plug
it back in. The cooler should now start up correctly.
