Im new to the community and cnc machines. I bought a homemade cnc machine, its 3 axis, the cutting area is 2x2 and it has a 2 1/4 hp router. The machine came with a desktop computer with mach 3 and 2-3d cut software. Before purchasing the machine i seen it work, I do not have any experience at all.. LOL.. I have downloaded trail software before hand and can do some design but Im having a problem with mach 3. My first question is do I need to recalibrate the machine do to it being unplugged ? When the owner was showing me the machine, he had mach 3 opened and there were arrows to move the axis but now there isnt, not sure if he hit another button to hve that option open or not ? Im really interested in learning and getting this machine to work for me and start small projects. Any help is appreciated.. Thank you
