Hi all I've purchased a nearly new CNC milling Machine 8x4 1 x cylinder overhead gantry Chinese 1325 model no. Its currently running mach 3 controller software. I've always used ncstudio, this seems very complicated in comparison. I'm having trouble with the Z axis, I don't believe mach 3 knows the limits of the z axis, as it regularly tops out and I get an error limit switch reached.

What I need to know is can anyone help me in specifying my z axis mechanical limits within mach 3, X and Y axis has been set by previous owner.

Or

Can I run my CNC on ncstudio (and where can I find a suitable downloader) so I know how to input CNC mechanical data and like the simpler interface
