I am new to the laser cutting world and have no idea what this means or how reconcile the problem. We had the machine installed several months ago and had someone come in to re-commission the machine, fix any issues, tune it in, and have it cutting parts before they left. They did so and did a FABULOUS job! Within a few days of his leaving I went to setup my first actual job on it and ran into this issue and have been stuck ever since.
Anyone out there ever encountered this before and know how to resolve this? I could take some pictures of the control with these alarms present if need be but, this is all the info that I could glean from the alarm/error page displayed.
