I have a new install of Mach3 Demo to set up my machine. I have configured my travel limits to all come in on 1 port pin because of limited inputs from my breakout board. This works fine, for a few minutes. Here is the situation, when I first start Mach and begin to jog my machine if I hit a travel limit the machine stops and tell me in Mach that a travel limit has been tripped. I reset Mach and all is well. However, after jogging a few minutes the travel limits no longer stop Mach from operating. When I go into diagnostics I can see that the travel limits are in fact coming on when I press them but Mach continues to run. This happens every time I start Mach after about 5 minutes of machine motion.
Anybody know what could cause this?
Thanks,
Scott
