ok Hood i will go and get a copy of it from the computer its on. Now ger21 asked if I had a 64 bit computer and I said no. so i went out to the computer used for Mach3 and it says i have " Windows XP Proffessional Version 2002 Service Pack 3". I didnt see anything about 64 bit or 32 bit. is there some place in particular i should look? testing result at the port pins 1 thru 12 .08 volts pins 10,11,12,13 and 15 4.31 volts pin 14, 16,and 17 .08 volts pins 18 thru 25 .01 volts. with Mach3 open pins 2,3,4,5,6,7 show no voltage movement when i hit the jog keys but the dro in the MIDI tab show that it sending a signsl. i will go get the xml file you asked for and send it shortly.
