I have one switch located on each of the X-, Y+, and Z+ end of axes travels, and have the X HOME, X--, Y HOME, Y++, and Z HOME, Z++ inputs enabled. The problem is the RESET LED after 3 - 4 seconds keeps flashing, even after hitting RESET again. The only way I can prevent this from happening is to disable X--, Y++, and Z++ limits. Can anyone assist me in solving this problem?
