I don't see any of the other post I made nor did I get any resolution to my problem, I have went through videos, manual and any of the advice I could find on the subject on you forum, I new to cnc, and have been able to do something with my machine, but knowing that its not correct bothers me, I want the machine to work the way its suppose to. My biggest problem has been setting the home limits on my machine, when i go to the diagnostic page and press the home switches nothing happens, and there are no instructions as to how to make them turn on. So today I'm at wits end and will probably do a reinstallation of Mach3 to see if the home lights come on at all. I've gone over everything else at least twice. could use a little knowledge from someone.
