To bad you couldn't buy the machine and have them knock off the cost of the overpriced control! Then set the machine up with Mach3!
Why would anyone sell a cnc machine ($8 - $13,000) without limit switches (How generic can you get!) I couldn't find anything about limit switches on their site. Did they tell you they are not included ?
If your buying the machine anyway, just buy it without the limit switches. Then add your own (Yes you
have to have them!) On the "Shop Sabre" site, they claim you can add custom "M-Codes". So add a hardware switch, and a soft limit switch.
The $750 is what we call price gouging! Thats about like the Bozos that try and charge close to a grand for a floppy drive!
