I am rnning MACH3 with the TH300A torch height controller with a Campbell Designs breakout board. I was having several issues with the software so I reloaded all of the programs and now everything works except when I reset MACH3 it goes into a limit tripped mode. I unhooked all of the sigal wires to the breakout board and still have the problem. I did not have this problem before reloading the program.
