Hello all,

I have been having a browse to see if I can find an answer to my issue but haven't found anything definitive yet, so I thought I would ask!

We have here an old 2007 super mini mill that is having some issues.

The spindle won't rotate under power, but even with an M03 Sxxx command sent you can move the spindle freely. But the spindle load goes up to max.
if you try and orient the spindle for any reason (tool change etc.) it throws up alarm 116
there are no fault lights on the vector drive until or any other boards in the back
if you rotate the spindle by hand it displays the correct RPM on the control.

Does anyone have an idea as to what could be causing the issue, rather than going with Haas' idea and replacing the whole vector drive unit for about £6000
