Twice today while doing some testing with my new E2 I’ve had the material I was using shift for no apparent reason on the cutting mats. The laser wasn’t touched while it was running but the material just moved. I’m suspecting that it might be the air-assist causing vibrations causing the material to eventually shift. My question is if you are using the cutting mats, what are you using to keep the material in place? Would rare earth magnets hold the wood in place though the mats? Looking for some ideas.
