can anyone help me i have a 2year old vm1 ,i started the machine up and calibrated it ready to put in a programme and a customer came to talk to me and after about 10 mins. i heard it exhaust the air as it does if left for a period of time when i went back to work with it there was a fault on x axis showing on screen which hurco tech guy said was cable disconnected or a motor fault , this did not appear to be the case, a.nd eventually i swapped the wires over on the x and y drives and the fault stayed with the same servopack , i suspect the servopack is faulty or is there any other explanation. thanks in advance merv385
