Hi Guys..i need help..not sure if I am posting in the right thread... I have Hartford VMC with Mitsubishi controller on it - MELDAS M3 --- It keeps forgetting the reference i.e. When I start the machine and send it to reference it goes there well and Shows X,Y,Z as Zero... But from there it does not come to G54 or G55 Correctly and misguides to different coordinates. After reference I tried to give command in MDI as G92 G53 X0 Y0 Z0; then main MONITOR screen Coordinates gets the value of G54 and it some times works fine but that's intermittent only. Very confusing as it gives me fear of having an accident and spoiling the job. I have got the Battery also replaced last week but it did not help. not getting any support from Mitsubishi so far so looking on you guys to help if possible. Thanks
