Re: [CAD_CAM_EDM_DRO] cnc mill project

well, i have a Xylotec controller and size 23 steppers (bipolar) supplied by
the ever helpful guys at Simply Cnc, and have a "Cobra" style mill fully
cnc'ed up with it and i must say it flys along and is perfectly capable of
both rapid router type work and is happy to chew its way through cast iron,
steel, alloy etc at a lesser rate of knots ( faster actually but that gets
expensive in endmills!).
I suggest you speak to the guys at Simply Cnc Tel 01292 311377, they have
already worked around the sort of problems you may encounter.
