My less-than-one-year-old G0720R benchtop mill died. In the middle of drilling some small holes, I pushed the Start button and got only a small click. Some diagnostic work determined that some of the power transistors on the inverter board had shorted out. I have no clue as to why they died when the machine was under no load or even stopped.
Does anyone have experience with inverter problems on this machine?
Grizzly have agreed to send me a new inverter board, but would not tell me when I might get it--including the possibility that it might have to come from China.
Has anyone swapped out the supplied inverter for another type? Is this sort of failure common?
Any ideas about what I can do to fix and avoid this problem in the future will be appreciated.
