Hello. We have just powered up our vmc. I cannot get the spindle to rotate. If I press the jog spindle button the door lock actives and load goes up but nothing is moving. I then get a spindle overload alarm. I do have a ref z alarm but not sure if this would cause the spindle to overload and not spin. Does anyone have any experience or advice. I will sort the z ref alarm tomorrow. Thank

Is it possible that there is an wiring problem?
If the load meter moves, and overload alarm occurs, it seems like it is trying to run.
Yes I can turn the bottom of the spindle by hand

Could be a wiring issue we have only just brought the machine (second hand). This is the first time we have turned it on. Not sure where to start.
