Re: BOSS Retrofit...Little details

If your mill came with limit switches they should be ok...Mach2 can
use NO or NC...As for the motor wire, i looked at jameco's web site
and could not find anything suitable...I have been looking for motor
wire myself. So far all i can find is $3 per foot stuff...The
minimum wire size you want to go with is 14, good for 15 amps. 12
guage would take you to 20 amps. 10 guage 30 amp...And yes shielded
is very good idea. You also need fine stranding to...

For a example of very good wire oil resistant, fine strand, shielded,
go to alphawire.com
http://www.alphawire.com/pages/91.cfm
the cable on this page is about $3 foot from wire distributor.
