Hi,
I have an SX3 that keeps blowing the main fuse located next to the EMI filter, not the one on the PCB. It will blow as soon as power is applied to the machine without pressing any buttons. Any idea what could be wrong? I have checked the obvious things. The spindle travel dro isn't touching anything. I have disconnected the U - V - W motor terminals from the PCB and still the same thing happens.
I have done a visual inspection of the PCB and can't see any issues with it.
Any idea what it could be, is this a common problem?
Thanks
