HELP - 3D CNC design & running programs & PCs.

Thank you. Will check them out. I expect it'll cost something to sort it out. The machine belongs to the Mens Shed I know I can get it covered as long as it's reasonable. One intermittent issue we've been working on is 'interruptions' of the axis but Mach3 just keeps going resulting in the X, Y or Z axis is out of sync & it stuffs the whole job up. We've only just put on shielded cable to the 4 axis drive motors & have a surge protector in the power line.

I'm in Ulladulla, south coast NSW. Not too far away except I'm a full-time carer.

Yeah. I've been looking into this & another . VERY interesting. I see what you mean by a budget. I'm running a Miller machine with 4 axis & VFD. Do you know off hand who has tried this with these components. It would aid me a real lot as I'm trying to jump the barrier around the USB input card & still use my current gear. It has all opened up many many questions such as colsed loop stepper motors but the still come with a similar controler unit as the link below.
