The laser cutter is currently down due to an alignment issue - hopefully I will be able to attend to this tomorrow.
Please do not use it until a lase maintainer has returned it to service.
Thanks,
Greg
The laser has been returned to service. The fault was found to be that the air assist nozzle screw had worked loose and the nozzle had fallen into the path of the beam, supported by the air assist hose. The nozzle has been put back in the proper position and the screw replaced. If you notice anything falling off the laser, please report this.
