I was working on the Bridgeport MDI CNC mill, ( Heidenhain 145 control) trial setting a programme, and forgetting that I hadn't switched on the air compressor.
As the programme went through its sequences I realised the sequence stopped because the motor wasn't switched on. ( has to have the manual motor switch to the on position)Having set the switch to on, I then set the sequence off again, but this time I could smell burning.
Restarted, ran the sequence, spindle turned at 3 rpm and stopped. I then realised the machine has an air brake, so figured that was the burning.
Machine seems to have gone into fault mode, so I switched off at mains, then back on again, the cnc control lights up, says power interrupted, pressing the main power button wont power up the main electrics for the spindle and feeds. I checked the 5 fuses in the control cabinet and 3 on the wall, all ok?
Typically, promised urgent job for Monday.
