Hello everyone, I'm fairly new to the cnc world. I have a friend who built me a "starter" cnc machine so that I can learn with. It uses a Dremel tool cutter. I've had it about 4 years but only used it a few times to make a few small projects. Now that I'm retired I really want to learn more however my machine doesn't seem to want to communicate with my PC and Mach3. So I've come here to read, learn and trouble shoot my issue. I hope to comb through all the posts to find the answers to my issues. Anyway, here are a few photos of my small machine.
