Hi Doddy ,
Sorry for the delay just got back from hols , I have just bought a multimeter I have had a beam out of laser so I know it works it is brand new .On the g540 main terminal block I have 48 V going in on pin 1 and 2.I cannot get a reading out of pins 7 , 8 and 9 .pins 1 2 3 and 4 are are showing 11V.I am a total newby to electronics I can take some screen shots of of Mach3 to if it helps to see if I have pins and ports etc set right . Kind regards Phil
