I'm not exactly new here, just new to posting as of today. I got into CNC by helping a friend. I was never interested in CNC work, instead one of my big hobbies is stained and fused glass.
I'm an engineer, he's not, and so he asked me to take a pile of surplus tables and Compumotor parts and build something. One thing led to another and he had his second mill, but unfortunately it was running Compumotor's 6000 series software in 2015 (yes, it still lives). I built him exactly what he asked for but not what he needed and so I upgraded his mill to Mach3 and he's now doing very well.
I had fun playing with the mill I had built but then I had to give it away and I was mill-less. To fill the void using the rest of the surplus parts I built a second mill for myself. However, my friend was transforming from strictly a hobby to hobby-plus and selling his wares online. He needed another mill for specialty work and so I sold him my second mill.
Now I've build a much larger third mill (~17"x22" cutting area) where I can cut wood and engrave glass (in a water bath). Merging mill and kiln operations has greatly increased the variety of what I can do with the medium.
