General Mach Discussion / help please

« on: April 20, 2012, 03:18:11 PM »

hi, looking for any and all input . i got done retrofitting my machine with pmdx boards they work great also using a vfd and leadshine drivers . problem i have is when i run a part program i get alot of different reasons the program stopped running . i get external e-stop , limit switches tripped . go to f7 page and no inputs are on for the e-stop or limit switches. sometimes the program will run none stop for 10 times and then it will not make it past the 1 or second hole .

things i have done

moved vfd out of control box with the 126 board and drivers
added safety grounds
changer power supply for 110
installed a filter for line voltage .


open to any ideas going bald here .
