Help with Unity controller

[Rick_knecht]

My Asteroid has run well for three years. However today when i went to start it, the power light illuminates on the controller but there is no fan noise and the stepper motors do not click. LinusCNC states limit errors on all three axis. I I override limits and try to home the machine, the virtual display shows movement, but the physical machine does nothing.

Does the controller have a reset button? any help or direction would be MUCH appreciated.

Rick,

Did you ever get any help on this issue? Wondering if this forum is still actively moderated. Very few posts lately.
