My machine (Bridgeport Discovery 300 VMC) which only has limit swiches and no home switches -- the original controller doubled up this purpose. As part of my retrofit (7+ years algo) the Camsoft S/W required both limit and home, so I added the additonal switches. I now want to use Mach 3 (guess why!) -- When I setup Mach 3, can I go back to the way the machine was originally? Reason: the only switches I could mount, due to limited space, were those little micro switches with roller bearing ends -- they are not vibration and contaminate safe. I rather just get rid of them.
