Mike at CEM Lasers is very knowledgeable and helpful. I could not recommend anyone more highly for technical questions, maintenance or repair of your laser cutter. He has helped my department at UC Irvine several times over the past couple years with our Universal Laser Systems VLS 3.50 Desktop laser cutter. He troubleshoots our problems quickly and has even offered up his time and equipment -FREE of charge - to make the cuts I needed while he was ordering a replacement part for our machine. He is easy to communicate with and knows a tremendous amount about the hardware and software associated with laser cutters, and is happy to share what he knows with you. read more
