Re: lighting cables for CNC

Hi Andrew

Something like .75 mm2 (lighting flex) is fine for stepper motors.
Because they are current driven a little bit of loss in the cable
does not hurt, however you do need to be able carry 1.5 to 2 amps
(typical for most cnc steppers) per phase so you can't get away with
telephone wire or alarm cable. Try the electrical wholesalers you
may be able to get some 6 - 10 wire control cable where each wire is
a different colour and about .5 mm2. It makes life easier than using
twin flex and having to buzz it out after you loom it up as a cable.

On you server problem, if you are really keen on using it for win98
then format a floppy on the other system you have access to and check
the include system files check box. Put it in your server and reboot
it. You should then get the A: prompt. Type format c: which will
take everything off your c drive. When that is done put your startup
floppy back in and try installing win 98 again.

Cheers
Nigel
