Need some advice on testing the controller for my grizzly mini mill..
I think when I had the cnc spindle un plugged from the mill, I somehow think I reconnected it backwards and the 0-10v was connected to gnd and gnd to 0-10v to the mills control panel..
so I assuming the mills control panel is blown I get no spindle movement either in cnc mode or manual spindle mode.
when I power it up I hear what sounds like a relay clicking in the mills controller the small fan powers up and the green led lights up, if I turn the pot on the orange led lights up but no spindle even with the pot to full speed...
Any thoughts on this, or any test I can try to make sure its the mills controller ?
Thanks gary
