Thanks for the add. My boss just bought a new machine. It arrived last week. I seem to be the default operator due to previous CNC experience. So far the only complaint I have is the torchmate dongle. I is fragile. Very fragile. The third time we used it, It fried itself to my usb port. Fortunately our machine is new enough that our contacts with Lincoln are cooperating with us to get a replacement. Do you guys have plans to make these things out of something better built or have some other type of liscense security? Mike
